my daughter is of 10 + month now and was born premature in 7 1/2 month. till now she is not able to sit by her own, what should IDo. Her wait is 6.9 kg

A. Although preemies might learn to sit up a little later than their full-term peers, most preemies will learn to sit up by 9 months corrected age. If your baby is not sitting up for 9 months or is not using both hands to play while sitting by 12 months corrected age, talk to your pediatrician.
