Breastfeeding

So, I was formula feeding my daughter and she wasn’t tolerating it. I breastfed my daughter for like 5 minutes and she does good on it, but what are tips so she wants to take it? She takes it then a few minutes later she doesn’t want it then she does. It’s also hard for her to get my breast so I don’t know what to do about that.

I feel stupid asking this, but I just need some help. 😩
