My baby doesn’t sleep without feed and that too for an hr … he is 21 months old … how to stop it

A. Femite lotion you should apply this is going to help because it’s very bad taste so eventually the child is going to give up the second other thing that I would recommend you to take a medicine introduce water or milk before sleeping but then make the child brush the teeth before go to sleep otherwise the teeth will start to get spoiled and the child will get more stubborn to continue with the feet
