My baby doesn't want to stay sitting for long—is it weak muscles?

When I sit my baby up, they fall after a short time and don't want to stay sitting. Does this mean their muscles are weak?

When a baby who can't sit up on their own lets themselves fall after a few seconds when you hold them sitting, this is usually not weak muscles but rather developmental readiness. Babies typically start with supported sitting between 4-6 months, brief unsupported sitting between 6-8 months, and can move into a sitting position on their own by 8-9 months. If your baby is at the lower end of this range (4-5 months), letting themselves fall is expected behavior—their back and abdominal muscles haven't strengthened enough yet. However, if their head control isn't good, they're not using their arms and legs equally, or they're over 8 months and still can't sit for even a few seconds, I'd recommend having your pediatrician evaluate them.
