I have definitely seen a connection between circumcision and breastfeeding problems, and I think it is worse when done in the first 24 hours. I think the problem may be related to breastfeeding causing urination (as it frequently does) so that the baby associates nursing with the pain of urinating on his sore penis. I often see the baby start to nurse, then pull away, clearly upset, when he pees. Sometimes nursing the baby without a diaper (just lay a diaper or towel underneath the baby instead) is more comfortable. Teresa Pitman LLL Leader, Oakville, ON
