my baby is now 9 months old, but she was born pre term at 6 months. which formula can i offer her for better weight gain and digestion friendly.

A. Nan , Similac , Dexolac and mms all of them are good you can go for stage two of any of these milk and all of them a good brand of formula so since your child is nine months now you can easily go ahead with stage two and if you’re starting for the first and then give one for a month and then stage two afterwards
