YOUR QUESTION. A CLEARER NEXT STEP.
When do babies move from rolling over to sitting up?
Babies usually roll over by about 6 months and learn to sit independently between 6 and 9 months. Rolling builds the trunk strength and head control that sitting needs, so the skills flow naturally into each other. A month or two either side is normal; check in if there's no rolling or head control by around 9 months.

One day your baby is rocking from back to tummy — and a few weeks later they're propped up, taking in the whole room. That bridge from rolling to sitting is one of babyhood's loveliest leaps.
In short
Most babies roll over (both ways) by around 6 months and learn to sit up steadily on their own between 6 and 9 months. Rolling builds the trunk strength and head control that sitting needs, so the two skills naturally flow into each other over a few months. Every baby has their own pace, and a window of a month or two on either side is perfectly normal.
How the skills connect
Rolling and sitting aren't separate boxes to tick — they're stages of the same growing core strength.
- 4–6 months — your baby rolls front-to-back, then back-to-front, and begins pushing up on their forearms during tummy time.
- 6–7 months — they can sit with their hands propped in front (the "tripod" sit) for short bursts.
- 7–8 months — sitting becomes steadier and hands come free to reach for toys.
- 8–9 months — many babies learn to get themselves into sitting from lying down, and start pivoting toward crawling.
Plenty of floor time on the tummy is the single best way to help — it strengthens the neck, back and shoulders that sitting depends on.
When to check in
Milestones are a guide, not a stopwatch. It's worth a friendly developmental check if by around 9 months your baby isn't rolling at all, can't hold their head steady, seems very stiff or very floppy, or always uses just one side of their body. These aren't alarms — they're simply good reasons to have a quick look together.

Something to notice. Something to discuss.
What to notice
Have a friendly developmental check if, by around 9 months, your baby isn't rolling, can't hold their head steady, seems very stiff or floppy, or consistently uses only one side of the body.
In everyday life
Give plenty of supervised tummy time and place favourite toys just out of reach to one side — it encourages the rolling and trunk strength that sitting up depends on.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
At what age should my baby be sitting up on their own?
Most babies sit independently between 6 and 9 months. Earlier, they sit with their hands propped (the tripod position) before letting their hands go free to reach for toys.
Does rolling have to come before sitting?
Usually yes — rolling builds the neck, back and shoulder strength that sitting needs, so they tend to develop in sequence over a few months. Some babies vary the order, which can also be normal.
How can I help my baby learn to sit up?
Plenty of supervised tummy time is the best support, as it strengthens the core and head control. Brief, supported sitting with toys at eye level also helps once your baby has good head control.
When should I be concerned about late sitting?
It's worth a gentle developmental check if by around 9 months your baby isn't rolling at all, can't hold their head steady, seems very stiff or floppy, or always favours one side. This is for reassurance, not alarm.
