Your 6-Month-Old: Rolling Tummy to Back, Passing Things Hand to Hand
By the Growbaby team · Published Aug 4, 2026
Written against AAP, CDC and WHO guidance. How we write these guides
At a glance
- Rolling from tummy to back is the CDC's milestone for this month; back to tummy usually comes later.
- Objects get passed from one hand to the other, a real coordination milestone.
- Your baby turns deliberately toward a sound rather than just startling at it.
- Around 6 months is the usual guidance for starting solid food, alongside milk.
- Stop swaddling well before this point if you have not already.
Six months is a hinge. Your baby can now move themselves across the floor in some direction, even if it is only by rolling, and that changes the room. It is the month most families discover what is actually reachable from ground level.
It is also when solid food usually starts. Milk stays the main event for a while yet; the first months of solids are about learning that food exists, that it has textures, and that eating is something you do sitting up with other people.
What is new this month
Rolling changes the room before it changes anything else. The CDC's milestone this month is rolling from tummy to back, and back to tummy generally follows later, because it needs a deliberate push rather than a topple. Either way a baby who turns over can now travel a short distance without meaning to, which is usually the week families discover what is actually reachable at floor level.
Passing an object from one hand to the other looks minor and takes real coordination: two hands, one intention, and a handover in the middle. It is also the first time your baby can keep hold of something while doing something else with the free hand.
What the CDC checklist says at 6 months
Six months is one of the ages the CDC publishes a milestone checklist for, which makes it worth stating precisely rather than paraphrasing. These are things most children, meaning 75% or more, can do by this age.
- Social: knows familiar people, likes looking at themselves in a mirror, laughs
- Communication: takes turns making sounds with you, blows raspberries, makes squealing noises
- Thinking: puts things in their mouth to explore them, reaches to grab a toy they want, closes lips to show they do not want more food
- Movement: rolls from tummy to back, pushes up with straight arms while on the tummy, leans on hands to support themselves while sitting
What is not on the six-month list
Two absences are worth knowing, because both get reported as six-month milestones elsewhere and neither is one.
Sitting without support is not here. What is here is leaning on the hands, the tripod position, which is a different and less stable thing. Unsupported sitting appears on the nine-month list, along with getting into the position without help.
Rolling from back to tummy is not here either, and in fact it is not on any CDC list at any age. Only tummy to back is, and only at this month. Our guides to sitting up and to rolling over cover both in full, including what the gap means if your baby is doing one and not the other.
When to raise something
Bring it up at the six-month checkup if your baby is not rolling at all in either direction, cannot hold their head steady, does not reach for things, or does not respond to sounds around them. The same goes at any age for a consistent difference between the two sides of the body, or a skill that has gone away.
None of these means something is wrong. They mean the question belongs with someone who can watch your baby, and six months is a visit you already have booked.
Week by week, in the app
One thing to notice and one thing to try, for every week of the first three years. Here is what this month covers. The app works out which week your child is in from their birth date and brings each one to you on the day.
- Week 23Your baby is Transferring Objects
- Week 24Your baby is Rolling Over Completely
- Week 25Your baby is Turning Toward Sounds
- Week 26Your baby is Reaching and Pulling Objects

This week, for your baby
Growbaby works out which week your baby is in from their birth date and brings that week's activity to you on the day, so you are not looking up where you are. Plus adaptive soothing for the nights and Growy for the questions in between.
Frequently asked questions
Around six months is the usual guidance, alongside milk rather than instead of it. The first months of solids are about learning that food exists, that it has textures, and that eating is something you do sitting up with other people.
Well before your baby can roll, which for many babies is now. A swaddled baby who rolls to their front cannot push up or turn their head freely, so the swaddle has to go the moment rolling looks possible, not the moment it happens.
Both hands acting on one object, with one letting go exactly as the other takes hold. The practical result is that your baby can now keep hold of something and still reach for the next thing, which is why floor play and mealtimes both get busier this month.
