Chloe reached out and grabbed my nipple really fast this morning. When she pulled back, it hurt really bad. I thought she just pinched it but upon observation just now, I noticed I have a slice under my nipple. No wonder why it hurts so much when she nurses. I never even experienced this pain when nursing my newborns. I have been putting breastmilk on it, but it really hurts when it is wet

Do these things take forever to heal? Man Chloe is awake from her nap and is gonna want to nursie... about to go grit my teeth.
Thanks in advance!!!!
