Inverted nipples and successful breastfeeding

When my baby was born I never thought I would be able to breastfeed my baby without a nipple guard. She had such a difficult time trying to eat the first few days. Luckily I could use the nipple guard. Five and a half months later I tried without it, because I thought I lost the nipple guard, and it successfully worked! Maked me feel like I was like everyone else and nothing was wrong with me
