respected dr, my baby birth weight 2.3kg and preterm baby .im giving pre nan powder .now my baby 4months old 5.5kg can I switch to pre nan to nan pro 1 ?

A. Yep you can switch to stage one there is no problem in that case and also I would recommend you to start with stage two once your child completes the time of 7 to 8 months since it’s a premature child I would advise you to push the stage two since you’re starting with stage one now
