My dd is 13 weeks and has happily been ebf. In the last two days she's been getting really upset at Feds - writhing around, kicking her legs and crying. I feel awful as I don't know how to help her. I've tried burping her more but that doesn't seem to help. It does seem worse in the evenings so I don't know if it's a supply issue. I haven't tried expressing yet but am not sure if this would help. Had anyone had this or does anyone have any ideas!
