Sits with support

What is this milestone?

Sits when propped up

At this stage, your baby can maintain a seated position when propped up by pillows, a supportive seat, or your hands, holding their head steady for extended periods.

Why it matters

Sitting with support opens up a whole new vantage point for your baby. It allows them to engage their hands in play while sitting, developing hand-eye coordination, and it prepares the core muscles for independent sitting.

What to expect leading up to it

They will likely be quite wobbly at first, often leaning forward heavily on their hands in a 'tripod' position. You'll notice their balance slowly improving as their lower back muscles gain strength.

How to encourage and support it

Sit them on your lap facing outward, or sit on the floor with your legs around them so that you are the support. Do not prop your baby with nursing pillows, cushions, or rolled blankets — pillows are not a safe support for a baby who can topple, and nursing pillows should only be used for feeding while you are holding and watching your baby. Never leave a propped baby unattended. Place engaging toys in their lap to encourage them to reach and play while maintaining balance.

When to talk to your doctor

Bring it up if your baby cannot sit propped up with support by around 6 months, if their back stays very rounded and they cannot hold their head up while seated, or if they seem unusually stiff or floppy. And at any age, if your baby loses a skill they already had, tell your pediatrician that week.
