teqrs coming out form one eye from my 3 month old baby...what could be the reason?

babies still learning to shed tears. don't worry.

uski eyes mei apni feed dhaalo it will bhi fine
put 2 drops in both eyes

If baby is crying and shedding tears only from one eye then mention this to the baby's doctor. we have tear ducts in our eyes and if one is blocked then that eye will not shed tears.
