My son is 13 months old and 8 kg weight. He is having loose motion over a week. I have given him Oflomac-M and Sporlac tablet twice a day. As he did not suffice, stopped giving him Amul milk and started Isomil. Later he was fine for the next 2 days and when I started back Amul milk since yesterday, again the stools are thin. As of now I am giving him Darolac twice a day. Should I give Zinc supplement for him? I am feeding him with tapioca water, curd rice, and rusk. Stopped biscuits also. He is absolutely fine and active. Was the medication sufficient? If not please suggest for his speedy recovery. Is this because of lactose intolerance? Do I need to stop feeding him on packaged milk? Currently we are using Amul. Thanks in advance for your response.
