Can i give my 8 months baby medication for appetite she don't like any type of food my peditration gave me a diet for her but shes refusing the food ?

No....: 8 month old doesn't need any appetite stimulant. As long as she doesn't have any issue/disease, e.G metabolic, gi, respiratory, cardiac, etc, not to worry. Check her growth chart: height, weight, head circumference, if these falls within the range, she is ok. She can have cereals, mixed pureed table/jar food, milk. 6 months and above kids get protein.
