What to Expect
Six months feels like a big one.
Half a year has somehow passed, and the tiny newborn you brought home may now be laughing, grabbing everything within reach, making all kinds of sounds, and becoming very interested in what everyone else is doing.
You may also notice bigger physical changes around this age. Sitting is getting closer, rolling may be happening more often, and your baby may be reaching for toys with much more purpose.
But six months can also bring another round of comparison.
Is my baby supposed to sit alone?
Should they be babbling already?
Why is another baby crawling?
Remember: 6-month baby milestones are helpful guides, not deadlines. Babies develop at slightly different speeds, and what matters most is continued progress.
Sitting Is Becoming a Big Developmental Focus
Around six months, many babies are getting stronger through their neck, back, and core.
Your baby may sit with support or briefly balance while leaning forward on their hands.
Some babies can sit independently for short periods.
Others need more time.
There is no need to constantly prop your baby into a sitting position before they are ready. Give them plenty of supervised floor time where they can roll, reach, push, and naturally build the muscles needed for sitting.
Reaching Is Much More Intentional
That toy across the mat is no longer just something interesting to look at.
Your baby may really want it.
At six months, reaching and grabbing can become much more coordinated. Your baby may hold toys, move objects between their hands, bang things together, and immediately put almost everything into their mouth.
This is how they explore.
Give them safe objects with different shapes and textures, but keep anything small enough to become a choking hazard well out of reach.
Their hands are getting quicker.
And soon, so will they.
Rolling May Become Their Preferred Transportation
Before crawling comes rolling.
For some babies, anyway.
Your six-month-old may roll from back to tummy and tummy to back, sometimes repeatedly enough to move surprisingly far across the floor.
Other babies may still prefer staying in one spot.
Both can happen.
Regular supervised floor play gives your baby space to develop strength and experiment with movement.
It also means now is a very good time to look around your home and realize how many things will eventually need baby-proofing.
Mobility can arrive faster than expected.
Your Baby May Be Laughing a Lot More
Six-month-olds can be wonderfully social.
Your baby may recognize familiar people, smile when you appear, laugh during play, and become excited when you interact.
Peek-a-boo may suddenly become one of the funniest things ever invented.
Your baby is learning that interaction goes back and forth.
You smile.
They smile.
You make a funny sound.
They laugh.
You repeat it approximately forty times because that laugh is impossible to resist.
These ordinary interactions support social and communication development.
Babbling Is Getting More Interesting
You may hear more combinations of sounds around this stage.
Your baby might experiment with repeated noises or change their tone as though they are genuinely telling you something important.
Respond.
Talk back.
Copy sounds.
Read aloud.
Sing.
Tell your baby what you are doing throughout the day.
Language development starts long before clear first words. Your baby is already learning that sounds have meaning and that communication involves taking turns.
Your Baby Knows Familiar People
By six months, your baby may react differently to people they know well.
They may light up when you enter the room.
Reach toward you.
Watch unfamiliar people carefully.
Or take a little time to warm up to someone new.
This growing awareness is part of social development.
You do not need to force your baby to interact with everyone.
Let them observe from the safety of your arms if that is where they feel comfortable.
Solid Foods May Be Entering the Picture
For many Canadian families, around six months is when complementary foods begin alongside breast milk or infant formula.
Your baby should show signs of developmental readiness, and Canada’s infant-feeding guidance recommends beginning with iron-rich foods.
This is not about replacing milk feeds overnight.
Food at this stage is also about learning.
New tastes.
New textures.
Using the mouth differently.
Sitting during meals.
Eventually learning to pick up food.
And creating an astonishing amount of mess from a very small serving.
If you are unsure whether your baby is ready for complementary foods, discuss it with their healthcare provider.
Feeding Does Not Need to Become Complicated
Starting solids can make parents feel like they suddenly need to become infant nutrition experts.
You do not.
Introduce age-appropriate foods gradually, follow safe preparation practices, and pay attention to your baby’s cues.
Some foods will be accepted immediately.
Others will receive a facial expression that suggests you have personally betrayed your baby.
That is okay.
Babies often need repeated opportunities to experience new foods.
The goal is exploration and gradual learning, not getting your baby to eat a perfect meal on day one.
Your Baby May Start Showing Clear Preferences
Six months can bring more personality.
Your baby may have a favourite toy.
A favourite song.
A favourite person to make them laugh.
They may become excited when they see something familiar or frustrated when you take an object away.
Those reactions are part of growing awareness.
Your baby is beginning to understand more about what is happening around them — even though they cannot tell you what they are thinking yet.
Play Is Still Surprisingly Simple
You do not need complicated toys to support six-month baby development.
Try simple things.
Read together.
Sing.
Play peek-a-boo.
Put safe toys slightly within reach.
Let your baby explore different textures.
Spend time together on the floor.
Talk during diaper changes and meals.
Your baby learns through ordinary interaction much more than through products marketed as essential for development.
Baby-Proofing Should Be Moving Up Your List
Your baby may not crawl yet.
But they are getting closer to being mobile.
Start looking around your home now.
Cords.
Small objects.
Unstable furniture.
Cleaning products.
Medications.
Sharp edges.
Anything within future grabbing distance.
It is much easier to make your home safer gradually than to discover your baby can suddenly cross the room while you are trying to baby-proof it.
What If My Baby Is Not Sitting Yet?
This is one of the biggest six-month milestone worries.
Independent sitting does not need to happen exactly at six months.
Some babies sit earlier.
Others continue developing balance for several more weeks or months.
Look at overall progress.
Is your baby gaining strength?
Controlling their head?
Reaching?
Rolling or attempting movement?
Using both sides of their body?
If you are worried about their physical development, talk with your baby’s healthcare provider.
What If My Baby Is Not Crawling?
Your six-month-old does not need to be crawling.
Many babies will not crawl for several more months.
Some may eventually use different ways of moving, such as scooting or rolling, before they begin pulling up and walking.
There is no reason to rush crawling simply because another six-month-old has started.
Give your baby safe floor space and let movement develop naturally.
Sleep May Still Be Changing
Six months does not automatically mean twelve peaceful hours every night.
Some babies sleep longer stretches.
Some still wake.
Teething, illness, hunger, developmental changes, and individual sleep patterns can all affect nights.
Continue following safe sleep practices and speak with your healthcare provider if you have concerns about your baby’s sleep, breathing, feeding, or growth.
Do not turn sleep into another developmental competition.
When Should You Talk to Your Baby’s Healthcare Provider?
Bring up any concern that stays on your mind.
Talk with your baby’s healthcare provider if your baby does not seem to respond to sounds or familiar people, has difficulty controlling their head or body, seems unusually stiff or floppy, uses one side very differently from the other, or loses a skill they previously had.
You do not need to determine whether something is a developmental delay yourself.
Your healthcare provider can help assess the whole picture.
One Last Thing, Mom
Six months can make it feel like everything is happening at once.
Sitting.
Food.
Rolling.
Babbling.
Laughing.
Reaching for things you were completely sure were too far away.
But your baby does not need to master the entire next stage this month.
Give them room to move.
Talk to them.
Let meals be messy.
Play together.
Celebrate the skills that are appearing instead of worrying about the ones that have not arrived yet.
Half a year has already changed your baby so much.
There is still plenty of time for everything that comes next.
