My newborn has been breastfeeding since birth for about 20-30 minutes every 3-4 hours. Today she she latched on and wouldn’t stop no matter when I tried to remove her. I’m saying probably over an hour. I have a slight pain when feeding anyways and use formula or pumped milk here and there when my breast are in remission. Never had a problem until today. She can’t possibly be that hungry when I haven’t changed the routine. Help! Is she really still that hungry?
