Month 10 — Standing, Understanding, and a Personality That Won’t Quit
Your baby has a personality, and they would like you to know about it.
Month ten is when the opinions arrive. Not vague preferences. Not gentle leanings. Full, visible, non-negotiable opinions about the way things should be. The right cup. The right toy. The right person holding them at any given moment. The right song, the right book, the right order of the bedtime routine, and heaven help anyone who gets it wrong.
This is not defiance. This is a brain that has developed enough to know what it wants and a temperament that has crystallized enough to express it. Your baby is becoming a specific person, not a generic baby, but this baby, with these preferences and that expression and a way of making their feelings known that is entirely, unmistakably their own.
And underneath the opinions, something quieter is happening.
They understand you. More than you realize. They know what “no” means, even if they choose to ignore it. They know what “food” means, and “bath,” and “outside,” and the name of the dog, and the sound of your car in the driveway. Their receptive vocabulary (the words they understand but can’t say) is growing at a rate that would stun you if you could see the full list. And somewhere in this month, the first real word might appear. A deliberate, meaningful, repeated word that means something specific. It might be “mama.” It might be “dada.” It might be “dog” or “no” or “ball.” Whatever it is, you’ll know it when you hear it, because it won’t sound like babbling anymore. It’ll sound like language.
Film everything this month. The standing, the words, the opinions, the problem-solving. Your baby is becoming a person at a pace that’s visible in real time, and the version of them that exists right now will be gone by month eleven.
What’s happening this month
Standing briefly without support. The cruising of last month has built enough leg strength and balance that your baby can now let go. Not for long, three seconds, maybe five, occasionally an extraordinary ten, before they grab onto something or sit down with a thump. But those few seconds of unsupported standing are the immediate precursor to walking, and they represent a remarkable feat of balance, muscle coordination, and nerve.
Understanding more words than they can say. This is one of the most fascinating asymmetries in child development. Your baby may only say one or two words, or none at all. But they understand dozens. “Where’s your cup?” They look at the cup. “Time for a bath.” They crawl toward the bathroom. “Give it to daddy.” They hold the object out. The comprehension is there. The production is still catching up, and the gap between the two is enormous.
Developing clear preferences. There is now a favourite toy. A favourite food. A favourite book that must be read six times in a row or the evening is ruined. A favourite person who is required for comfort and absolutely no substitute will be accepted. These preferences are real, consistent, and forcefully communicated. Your baby has a type, and they’re not subtle about it.
Mimicking sounds and gestures. The imitation that started last month is now more deliberate and more accurate. They’ll try to copy the sounds you make, not just the rhythm, but specific syllables. They’ll mimic gestures with increasing precision. If you brush your hair, they’ll try to brush theirs. If you talk on the phone, they’ll hold something to their ear. The copying is constant, and it means they’re watching you far more closely than you might think.
May say first meaningful word. This is the milestone every parent is listening for, and month ten is squarely in the window. A meaningful first word is different from babbling: it’s a specific sound, used consistently, to refer to a specific thing. “Ma-ma” every time they see you. “Da-da” when dad walks in. “Ba” every time they see a ball. It might not be perfectly pronounced. It might be a word only your family recognizes. But it’s real, and it’s the beginning of spoken language.
Problem-solving. Your baby is thinking. Visibly, tangibly thinking. A toy is under a blanket, and they lift the blanket to find it. A snack is on a shelf they can’t reach, and they pull a stool closer. A lid doesn’t come off, and they try turning it, then pulling it, then banging it on the floor. This is not random behaviour. This is cause-and-effect reasoning, and it’s happening in real time, right in front of you, executed by someone who can’t yet say the word “think.”
Film this before it’s gone
Eight ideas. Film whichever ones cross your path. Some of these happen once and never again. Some of them happen every day for a few weeks. All of them capture something specific about who your baby is at ten months old.
1. Free standing, where gravity always wins (but not right away)
Those three to five seconds when they’re standing alone are some of the most suspenseful footage you’ll ever capture. Everyone in the room freezes. The baby doesn’t know why you’re all staring. They’re just standing there, holding a block, having no idea they’ve let go of the table.
Film from a low angle to capture the full body. The wide stance. The arms held slightly out for balance. The look of concentration that suggests they’re doing advanced physics calculations. And then the wobble starts, and you can see in their face the exact moment they realize what’s happening, and then they sit down, or more accurately, they fall in a controlled manner that might generously be called sitting.
This footage is comedy, suspense, and milestone documentation rolled into one. The before-and-after of walking lives in these clips.
Sam and Nia captured free-standing moments with their babies that are impossible not to watch on repeat: the pause, the wobble, the graceful (or not graceful) return to earth. Every parent watching recognizes the held breath in the room.
2. First meaningful word
You might not be able to plan this one. The first word comes when it comes, at the dinner table, in the car, at 6am when you haven’t had coffee yet. But when you hear it, when you hear a sound that isn’t babbling but a deliberate, meaningful word directed at something or someone specific, get your phone out.
If you can, film the word and the context. “Mama” while reaching for you. “Dog” when the dog walks in. “More” at mealtime. The word alone is lovely, but the word plus the situation tells the whole story. This is your baby using language to communicate on purpose for the first time. That’s not a small thing. That’s one of the defining moments of human development, and it’s happening in your kitchen.
The Ingham Family documented first words across their children, and what makes the footage compelling is the reaction of the parents: the disbelief, the repetition (“Did you just say that? Say it again”), the scramble for the phone. The parent’s response is half the video.
3. The opinion face
Your baby now has a specific expression that means “I don’t like that.” You’ll know it. It might be a scrunched nose. A turned head. A full-body recoil. A look of betrayal that suggests you’ve committed an unforgivable act by offering the green vegetable instead of the orange one.
Film the food they reject. Film the toy they push away. Film the face they make when you try to put on the wrong jacket. The opinion face is comedy gold, and it’s also a genuine developmental milestone: your baby is asserting individual preferences, which means they have individual preferences, which means they’re becoming an individual.
Keep the camera ready at mealtimes this month. The range of expressions a ten-month-old can produce in response to a single spoonful of pureed broccoli is genuinely extraordinary.
Keren and Khoa from KKandbabyJ filmed their babies’ food reactions in compilations that became fan favourites: the dramatic refusal, the suspicious squint, the occasional pleasant surprise. Every face tells a story.

4. Problem solving
Put a toy under a blanket and watch them figure it out. This is object permanence in action (the understanding that things continue to exist even when you can’t see them) combined with the motor skills to do something about it.
Film the whole process. The confusion. The pause. The decision to lift the blanket. The triumph of finding the toy. Then try it again. Move the toy to a different spot. Put it behind a cushion. Stack cups over it. Watch your baby think. Visible thinking, in a person who couldn’t lift their own head ten months ago, is one of the most remarkable things you’ll ever witness.
The problem-solving extends beyond hidden objects. Film them trying to open a container. Film them stacking blocks and working out why the tower keeps falling. Film them trying to fit a shape through the wrong hole, then the right one. Every attempt is learning, and every failed attempt is learning faster.
The Bee Family documented problem-solving play at this age, and the footage is captivating because you can see the gears turning: the pause before each attempt, the adjustment after each failure, the satisfaction when it works.

5. Copying everything
Your baby is a mirror now, and the reflection is hilarious. Hand them a comb and they’ll try to brush their hair. Give them a phone and they’ll hold it to their ear. Pick up a broom and they’ll want one too. They are studying you constantly, and their study notes are physical.
Film a deliberate imitation game. Do something, then hand them the tool to try. Pretend to drink from a cup. Pretend to read a book. Pretend to sneeze. Their version of whatever you do will be an imperfect, exaggerated, deeply charming copy that reveals exactly how they see your actions.
This is also the month to be very careful about what you do in front of them, because they will attempt all of it. Including the things you’d rather they didn’t.
The McClure Twins’ parents filmed twin imitation games, and the footage doubles the comedy: two babies copying the same action in completely different ways, each absolutely certain their version is the correct one.
6. Playing independently
Step back. Film from a distance. Don’t say anything.
There will be moments this month when your baby is completely absorbed in play. Not interacting with you. Not looking for attention. Just… playing. Turning a toy over in their hands. Stacking and unstacking. Babbling to themselves. Existing in their own small world with total concentration.
This footage is different from everything else on this list. It’s quiet. It’s still. It captures your baby as they are when they don’t know anyone is watching, and there’s something profound about seeing a ten-month-old lost in thought. They’re not performing. They’re just being.
Film it from across the room. Use your zoom if you need to. The distance is part of what makes this footage special: you’re witnessing a moment that belongs entirely to them.
Tara Henderson included quiet, independent play footage in her milestone videos, and those clips stand out because they feel private and unforced, a baby in their element, needing nothing, content with their own company.
7. Book time
They turn the pages now. Backwards, sometimes. In clumps of three or four. Occasionally ripping the corner off a page with more enthusiasm than the binding can handle. But they are engaging with books as objects, and that engagement looks like this: they sit in your lap, they grab the book, they open it (upside down, possibly), they point at a picture, they make a sound, they turn a page, they point again.
Film from above, looking down at the book and their hands. Capture the pointing finger on the picture. Capture the page turn that skips from page two to page nine. Capture the moment they bring the book to their mouth because everything is still food at this age.
If they have a favourite book, and by month ten they probably have one they insist on repeatedly, film that one. The wear on the cover, the pages they always stop at, the sounds they make at specific pictures. It’s a portrait of a reader at the very beginning of reading.
JessFam filmed book time with her children across different ages, and the ten-month footage is always the most entertaining: the urgency of the page turns, the complete disregard for narrative sequence, the absolute insistence that this particular book be read again immediately.
8. The tantrum preview
It starts this month. Not a full tantrum (that’s coming later) but the first flashes of genuine frustration when they can’t do what they want.
They can’t reach the toy. They can’t open the drawer. They can’t make the block fit. And instead of moving on, they react. The face crumples. The body stiffens. A sound comes out that is not a cry and not a babble but something in between, a growl of pure infant frustration that is simultaneously alarming and funny.
Film it. Not to embarrass them later, but because this is a milestone too. The ability to feel frustrated requires the ability to have a goal, which requires the ability to plan, which requires the ability to imagine a future that’s different from the present. Your baby is angry because they’re smart enough to know what they want and not yet skilled enough to get it. That’s not a behaviour problem. That’s cognitive development in action.
Keep the clip short. Ten seconds of the frustration, then film the resolution: you helping them, or them figuring it out, or them moving on to something else. The full arc tells a better story than the frustration alone.
Elle and Jared captured early frustration moments in their family vlogs, and the footage works because they frame it honestly. This is what ten months looks like, including the hard parts. The moments where the baby’s ambition outpaces their ability are some of the most human footage on their channel.

One video idea for this month
“Everything baby understands at 10 months.”
Here’s the concept. Sit with your baby in a room with familiar objects and familiar people. Then test, on camera, every word you think they know.
“Where’s your ball?” See if they look. “Where’s daddy?” See if they turn. “Can you wave bye-bye?” See if they wave. “Where’s the dog?” “Where’s your bottle?” “Do you want food?” “Can you clap?” Go through as many words and phrases as you can think of.
Film their response to each one. Some will be instant and unmistakable: they look right at the thing. Some will be ambiguous, a vague turn, a delayed reaction. Some will get no response at all, and that’s fine. The video isn’t about getting a perfect score. It’s about documenting how much language your baby already understands at an age when most people assume they don’t know much.
Add a title card at the beginning listing all the words you’re going to test. Cross off each one they get right. The format is simple, satisfying, and endlessly shareable with grandparents who didn’t realize the baby knew the word “banana.”
If you want to go further, do the same test next month and the month after. The growth in comprehension is rapid and visible, and a side-by-side comparison at twelve months will show a vocabulary explosion that happened almost entirely in silence.
The Bee Family and Tara Henderson have both created “what does baby understand” content, and it consistently surprises viewers (including the parents themselves) how many words a pre-verbal baby has already absorbed. The footage is proof that your baby has been listening to every word you’ve said. Every single one.
Don’t worry about
Them not walking yet. The average age for first independent steps is twelve months, and “average” means half of all babies walk later than that. Some babies walk at nine months. Some walk at sixteen months. Standing and cruising at ten months means their body is preparing, and the timeline is their own. Do not let a social media video of a nine-month-old running laps around a living room convince you that your baby is behind. They’re not.
Not hearing a first word. Some babies say their first meaningful word at eight months. Some don’t say one until fourteen or fifteen months. The window is wide, and babies who talk later are not less intelligent. They’re often processing more language internally before they start producing it externally. If your baby understands words, responds to their name, and communicates through pointing and gestures, their language development is progressing exactly as it should.
The intensity of their preferences. When your ten-month-old screams because you gave them the blue cup instead of the green cup, it can feel like something is wrong. Nothing is wrong. They have a preference. They can’t regulate their emotions around it yet. Emotional regulation is a skill that develops over years, not months. Right now, the wrong cup is the worst thing that has ever happened to them, and they are allowed to feel that fully.
Stranger anxiety. If your baby cries when grandma tries to hold them, or clings to you when a friend visits, or loses it when the nursery worker approaches, that’s attachment working correctly. They know who their safe people are. They’re wary of everyone else. It’s not rudeness. It’s not a phase you caused. It’s a healthy, adaptive response that peaks around this age and gradually eases as their social world expands.
How much screen time they’ve had. If they’ve watched a few minutes of something while you ate a meal or took a shower, you have not damaged their brain. The guilt industrial complex around screen time is exhausting. Do what you need to do to survive the day. The baby will be fine.
The bottom line
Month ten is the month your baby stops being a baby in the general sense and starts being a specific, particular, unmistakable person. They have a favourite food and a favourite person and a favourite book and a way of making their displeasure known that is entirely their own. They stand on their own two feet, even if only for a few seconds. They understand your words, even if they can’t say them back. They solve problems. They feel frustration. They have opinions about cups.
This person is extraordinary. And they are changing so fast that the baby you’re looking at today will not be the same baby you’re looking at in three weeks. The standing will become stepping. The comprehension will become speech. The opinions will become sentences. And you’ll look back at this month and think: that was when they became who they are.
Film the standing. Film the word if it comes. Film the opinion face and the frustration growl and the quiet moment where they’re lost in play and don’t need you at all. Film the personality that won’t quit, because it’s only going to get louder from here.
And that’s not a warning. That’s a promise.
