ny baby is 3 years old and he still not able to drink milk because he is having milk allergy what should I do

A. ideally you must avoid the products if baby is allergic to it. baby could be lactose intolerant. it does get better with time in some babies. or another option would be to give homeopathic treatments. it has worked for one of my cousins. but not sure about the age when you can give. please check with your pediatrician.
