The first few days off colostrum were frustrating and
painful. I highly recommended lanolin nipple cream after every feeding. Once my milk came in about day 5 it was MUCH easier. My daughter latched really well, so I didn't find it painful, but they do get sore regardless. Try not to get frustrated, im still working on getting a steady supply in. Drink endless amounts of water, milk, juice, etc. Also, don't think if your breastfeeding you can't formula feed too.
