<human>: Hi I am Sasi from Chennai India. My baby boy just crossed 6 months and step into 7th month on 26th Dec 2013. From birth my baby is feeding with NAN PRO 1. On 25th Dec, we changed to NAN PRO 2. 2 hours after feeding baby affected by fever and got vamtings at evening. On 26th Dec night he is continuously crying for 3 to 4 hours and no fever at this time. When I taken to doctor on next day, Dr told that baby is doing good and no worries. But later also he cried for one to two hours for 3 to 4 times. I am not sure why this was happen? is it beacuse of NAN 2. If so which milk I need to feed my baby. Please clarify me with above question.
<bot>: Most formula milks are cow milk based and hence difficult to digest. Sometimes child Chat Doctor.  That could be due to the reason that NAN Pro 2 has not yet been tolerated well. After a few days, you can try it in double dilution and see if the problem persists. I think that it would go well. But rather than concentrating on which milk formula to give, I would rather suggest introducing semi-solid food items, introducing one new item a week. In due course milk would become just an optional item provided the nutrients get procured from other sources.
