I think I need help. DD2 (4 weeks tomorrow) won't stop crying unless I hold her upright and jig her up and down. She was throwing up profusely. HV mentioned reflux on wendesday, but said to feed her less and trust my instincts. Instincts shot to shit as I've had no sleep for two days. I phoned the MW this morning, who said phone the HV. HV said go to BFing support group. Baby is obviously in pain, but is it colic or reflux (hasn't thrown up for two days)? DH says phone a doctor. What should I do?
