For a while now ds2 has been really fussing at the breast for 99% of feeds. It takes him at least 10/15minutes to calm down and feed properly. Not great when I have ds1 demanding attention.
He hits and scratches at me, squirms and generally fusses. And then he seems to get lazy and if I don't guide my nipple into his mouth he just takes a mouthful of whatever is closest and starts sucking away.
It hurts and my boobs are covered in little bruises. 
Once he calms down and starts feeding properly he only takes 15/20 minutes to get what he needs but the fussing before we get there is really getting me down.
Does anyone have any idea why he might be doing this or if there's anyway to calm him so he feeds properly straight away?
