Baby becoming frustrated when feeding

Rachel

Hiya I have a 3 week old little girl, she used to latch onto my right breast really well and we never had any difficulties with latch (my left had cracks and blisters at the beginning)

The last couple of days she doesn’t seem to latch onto the breast very well she arches her back and shakes her head and gets into a bit of a state. When she does latch on it seems to come out easily and she gets quite irritable when sucking. Her arms and legs move and she makes groaning/grunting noises a lot. Sometimes she gets frustrated and cries. It also seems like she has quite a lot of the nipple/areola in her mouth and is pulling tugging at it.

Any ideas what might be wrong with her/the latch (I know it’s hard to tell without seeing it). She’s also feeds for a long time when she’s like this. I was really worried she wasn’t getting enough milk but when I squeeze my nipple milk comes out easily.

Thanks!
