My 4 month old baby has decided that my right boob is to be used as a pillow whilst feeding, and will twist his head round to rest on the centre of my chest, taking my nipple with him so it's pulled sideways. He's been finding his own latch for a while now, but this position makes it a terrible latch, sore nipple and the pressure of his head is giving me blocked ducts. I've tried different positions holding him, but he just twists his head round. I've also tried pushing his head back round straight in line with his body but he just resists me and goes back when I stop. He seems to drain my boob well when he wants, but swallows more air. He doesn't do it on the left breast. Any suggestions?
