Hi...Greetings from Kanchi Kamakoti CHILDS Trust Hospital, Chennai. I went through the history points you have provided - I understand your concern. I was expecting that there should have been a history of cow s milk and formula feed (this too contains cow s milk protein) given to the baby. I feel that your baby is having cow s milk protein allergy. Usually babies grow out of this sort of allergy by 1 year of age. My suggestions for you - 1. If still on breast feeds - Mother should go off cow s milk protein completely. This means that you should avoid consumption of anything and everything related to cow s milk - like - milk/ curds/ ghee/ butter milk/ chocolates/ biscuits/ ice creams etc. Even while buying commercial food products, you need to see the ingredients and if they contain milk - do not consume them. 2. Feed your baby only exclusive rice based feeds. But at 2.5 years it is highly unlikely that the baby is still having cow s milk protein allergy. I wish your kid a speedy recovery. If you need any future medical consultation and suggestions, I will be glad to help. You can approach me at the following link.
