baby is not gaining his weight ... give me some syrup or tonic even im giving him all weight gaining food also

A. Tonics Do not help in gaining weight it is just a mate it is it that they can just increase the immunity of a child can be the deficiencies in the body but that does not mean that it will help in increasing the weight you have to give proper diet and still if your child is not gaining weight then there is some issue with the body when the body is not adjusting with the food that is been given to the child
