Welcome to Health Care Magic. Your baby passing sticky stool should not be a problem, as long as the stool is not watery or mixed with blood and the baby does not have fever
and is gaining weight properly.
As for the baby fondling the nipple is normal and is supposed to act as a stimulus to produce more milk for the baby.
As for the medication that you are having for the liver
disease, if it is only vitamins
, it is OK, otherwise consult your Doctor and ascertain from the doctor, whether breastfeeding
is safe, while taking those drugs. Wishing you a very affectionate mother child relationship.
