why my 16 months old baby boy Drinking milk and water more and more but not eating food?? can anyone suggest about this

A. Common situation with kids water is not a problem but you cannot just continue to give milk to the child because actually either your child is having a sleep which is why your child is clinging more on having a milk that you are giving and not eating so you need to strike a balance in terms of food and milk to be given to the child
