I'm bf my 4 week DD1 and often having a problem getting her to latch on, particularly in the evening when she cluster feeds and my breasts and nipples get softer and floppy. She gets frustrated and wiggles around and slides off my nipple. Normally latch is good (when breasts are firmer) and I've checked her for wind and don't think it's the reason for the wriggling...
It sometimes helps to sort of squish my breast up with one hand to make it firmer - but that leaves me with wrist pain and arm ache (and no spare arm!)
Argh help!
