For the past 4 weeks my DD who is 19wks has been teething I think (dribbling loads, jamming her fist and fingers in her mouth and I can feel some ridgy bits, but nothing definite) and since then we've been really struggling with BF and I am wondering if the two are related? She makes a low groaning noise before feeding (but mainly only at night) and often makes this noise on the breast - sometimes it's like a cry. She latches on, but then whips her head off violently or pulls back really far and I can't get her to stay on. It's making me very sore and her very frustrated as she wants to feed and comes back with a wide mouth and tries to get back on. She also kicks her legs and brings them up like colic. Last night we tried some formula in a bottle and she did the same (I was worrying it was about low supply, but there's plenty of milk around when I squeeze and I can feel the letdown) . I have been rubbing a bit of Bonjela into her gums, but not much effect. Some feeds are ok, but some days she only has 1 or 2 good feeds where she stays on and nights are particularly bad. Has anyone experienced anything like this?
