Sitting up changes everything. Your baby can see the room, reach for toys and join in at mealtimes. Every baby gets there on their own schedule, but it helps to know the usual steps along the way.
The usual stages
- Steady head control. Many babies hold their head steady without support by around four months.
- Sitting with support. Somewhere around four to six months, many babies can sit propped up, or lean forward on their hands in a "tripod" sit.
- Sitting on their own. Most babies sit without support for a while by around nine months, and many do it sooner.
These are typical ranges, not deadlines. If you have questions about your baby's development, bring them up at your next checkup.
How to help your baby practice
Tummy time
Tummy time builds the neck, back and shoulder strength that sitting needs. Start with a few minutes at a time while your baby is awake and you're right there, and build up as they get stronger.
Supported sitting on the floor
Sit your baby between your legs or in a ring of cushions on the floor, and put a toy just in front of them so they reach and balance. Stay close, because wobbles and tip-overs are part of learning.
Floor play, lots of it
The more time babies spend moving freely on the floor, the more chances they have to roll, push up and try new positions.
Using a baby floor seat safely
A floor seat holds your baby upright for a short, supervised play session, like watching you fold laundry or playing with a toy in front of them. Our Mallow floor seat is inflatable, with a built-in pump in the center post, so there's no blowing it up by mouth. It's about 20 by 21 by 15 inches and deflates flat for trips to grandparents'.
A few rules keep floor seats safe:
- Floor only. Never on a table, sofa, bed or any raised surface. Never in or near water, and never as a float.
- Stay within arm's reach the whole time.
- Short sessions only, and never for sleep. If your baby gets drowsy, move them to their sleep space.
- Wait for steady head control before using one.
A floor seat is a helper, not a replacement for free floor play. Babies build strength by moving, so mix in plenty of time on a mat as well.
Once they're sitting
A baby who can sit is a baby who will soon be moving further, faster. It's a good time to look at our babyproofing checklist. Sitting up is also a sign that it's time to stop using a newborn bath support, since those are only for babies who can't yet sit or roll.
Questions parents ask
Is it OK to prop my baby up before they can sit?
Short, supervised supported sitting on the floor is fine once they have good head control. Stay right there, and keep sessions short.
How long can my baby sit in a floor seat?
Keep it to short sessions while you're within arm's reach, and balance it with plenty of free floor play.
What if my baby isn't sitting yet?
Babies develop at different rates. If you're concerned, talk to your pediatrician.
