breastfeeding

Annie
Okay I've been in the hospital with my baby girl and it's the fourth day and my milk hasn't came in and it's making me so frustrated because my nurses keep pressuring me to give her my boob but I get her to latch on but nothing comes out and we will be there for ten mins with no milk so I do the formula and it just makes me feel horrible when the nurses come in and say well you need to keep trying but it's like the more I try the more me and baby get frustrated 😩 does anybody else have this problem or had it? Please help me out mamas
