I have a fast letdown, which causes LO to have to gulp and pull off regularly to breathe, and choke fairly regularly, so he takes in quite a lot of air. He's therefore very windy, from both ends, though especially down. HV recommended gripe water, which seems to work to some degree, as does drumming fingers on his tummy (my DH discovered that one). But gripe water has e-numbers in it, and I felt so bad the first time I gave it to him that now something other than breastmilk had passed his lips . I have only given it to him once more after that, and felt guilty gain. Is there another option?
