I have a 4.5 week old baby and am using Avent bottles. The newborn teat nimber1 now seems to be too slow (she sucks way too hard and it takes ages to feed) but the next up seems too fast. Both give her terrible wind. What should I do? Her burps are impossible to get out and she ends up screaming all evening, which may be colic too but I’m not sure. Should I even swap bottles? I’vd Tried gripe water, infacol and colief but no improvement.
Thanks
