My DS is 3 months and usually when feeding scratches, pummels and grasps at my breasts. It is not nice! I interpreted it as wind making him uncomfortable but winding him doesn't make a difference. I swap breasts which helps for a bit but then he starts again. He even manages to get to them under a pulled down tshirt!
Is it a supply issue? He's putting on weight fine and has just started sleeping 11 hours through the night.
