Reply to Does anyone have twins and/or preemies and when did they start to sit on thei...

My LO wasn't born too prematurely but had a difficult birth with some time in the NICU. She started sitting on her own around 6 months. If they aren't showing any motivation I would see if physical therapy could help. My LO has been going since birth and it really helps. Otherwise my only recommendation would be to encourage it by playing more in sitting positions and teaching them how to sit up on their own by going through the motions with them. I hope that helps.
