question: Hello doctor, My friend's 2-year-old baby girl weighs 8.5 kg and is getting fever daily at 4 'o' clock in the morning for the last one week. After using the medicine, fever fades off at 11 a.m. and there is sometimes vomiting too. Also please help us to get rid of this issue. My friend has married his sister's daughter that is why the baby also is very lean. The doctor said because he has married in his immediate relation, the child is like this and the baby is very lean. Can you please suggest some medicine or food for the baby? If we feed anything also, she vomits. Please help.
