Sometimes mothers dont have the best diets, causing babies tummies to get upset. My sister in law loved junk and my niece had tummy aches and gas from mommys milk. My aunt ate well and her milk was not good enough for the baby. The baby was loosing wieght. I think every situation is different, all of us have tried different things until something worked. I would ask your mom what worked best with you and ask mom in law, sometimes its a hereditary thing. Hang in there!
