Hi...I went through the history points you have provided -
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. 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 you baby only exclusive breast feeds till 6 months of age and then start rice based feeds. As your baby is more than 6 months now - it is better to start rice based feeds.
3. If this is followed scrupulously - the baby will stop having
diarrhoea in another 3-4 days and then start gaining weight too.
4. If you feel your feeds alone are inadequate for the baby, then Zerolac is the only option.
Keep me posted about the recovery of the baby and follow of the case.
