Question: My daughter is 5 months old. When she was 20 days old we tried Similac (milk based formula), but she had repeated vomiting on that day. So we never tried formula milk after that thinking that she is allergic to formula though there might be other reasons. Later in her 4.5 month we tried Cerelac (wheat flavour) and she had repeated vomiting on that day too. Later we realised that Cerelac was too early for her. Now, as my wife is not able to produce enough milk for our baby, we planned to supplement her with formula milk, but we were afraid due to her allergic reaction earlier. So, today we met a Paediatrician and she told that baby might be allergic to cow milk based formula and she asked us to try Isomil (soy based formula), though she also told us to be ready anytime to go to hospital in case even if this formula does not suit my baby. Now we are very much in a dilemma on what formula to try - Similac again, or Isomil as suggested or Similac sensitive (which is special formula for sensitive stomach). Kindly advice us on this and how can we proceed. If this formula also not suits her, then what is our next course of action? Please help us.

thanks Doctor. I have one more query. How about the timing when we can feed the formula milk - like before breast feed or after. In day time or night time or both? And at the same time whether little breast milk and little formula milk can be given alternatively? or there should be some gap between breast feed and formula feed?
