inverted nipples?

Sami • Married to my soulmate(: mommy to 3 little beautiful boys. 3 year old, 1year old and a 4 month old💙💙💙👶👶👶
Has anyone else struggled with this I was planning on breast feeding but due to my nipples being inverted it's harder. Kinda feel like a failure at being a mom. I've tried nipple shields and for now I'm pumping but I'm really trying bc I want him to get his milk instead of formula. I'm trying to him some food bc I feel like he doesn't get enough :/
