When is the best time to examine breasts for lumps if breastfeeding. Common sense tells me to do it after I've fed my dd at night as she feeds on both sides and afterwards both boobs are about the same size and empty of milk. Also, how often should I examine and when as I don't have a monthly cycle to follow what with breastfeeding. Hope it's not a daft question but I've often wondered about it and at 31 it's about time I examined myself more regularly.
