Dd is 15 weeks old and, with the exception of some minor issues bf has gone well, she's gaining weight ok and seems to be getting enough. However over the last week or so she's become very fussy and feeding her has become really unpleasant; she'll thrash her little legs and arms around, latch on and shake her head around (this hurts), she grabs handfuls of boob and pulls at my boobs, she's started to bite me
(dreading her getting teeth!). I think a lot of it is down to her just being more interested in everything but it's becoming more like a wrestle than a bf. Just a phase? Any advice on how to stop it? Indicitive of a problem (supply maybe)??
