The baby is now one month old and for two weeks has had tummy troubles. I can't tell if it's colic or gas, he's really struggling. Massages and putting pressure on his belly don't help, chamomile tea, barley water, bio Gaia either. And I don't want to give him more chemicals. We follow a Gv diet. What should we do? ?
