Hi mommies, my 4 month old baby does not want to drink milk these days. He cries when ever i try to feed him. Other than feeding time he never cries. He is on comibation feed. He is not having more than 2-3 ounces at a time.; From a few days he is always trying to put his thumb into his mouth and he is always rolling over to lay on his tummy. Even during his sleep he is trying to roll over😂😂. What to do in this situation? I m worried about his weight gain. Plz advise.
