Thanks for your advise.
My question is not whether to change to 2號奶粉, but to try another brand of 2號奶粉. Aidan is now drinking Promil (S26 no. 2), since it is 肥仔奶粉, and I don't want Aidan to become too fat, so I am thinking to let him to try another brand. But he has no 熱氣, and health is good (touch wood!!) while drinking S26 and Promil, so I am struggling whether to change or not!
I also heard that the protein that in 1號奶粉 is better than 2號奶粉, so I asked a nurse from 惠氏 why we need to change to 2號奶粉 and why we can't let the baby drink 1號奶粉 even after 6 months, and she said the protein in 1號奶粉 is more easy for babies to digest and absorb, but as the babies need to eat solid food (adult food) eventually, so we need to let them to try some food which is less easy to digest and absorb (more close to adult food), in a transition period. That's is what I heard, not sure whether it's true.
That is, we can still feed with NO. 1 La..
My bb is 8-mth, is still feeding S-26 (i.e.No.1). Personally, I don't think it is 肥仔奶粉, coz my bb is still under weight. As my bb is still willing to drink No. 1, I really don't want to make a change. I don't like those No. 2 is with sugar in it in order to make bb drink more.
