Hi, I just had my daughter a week ago today and I have been trying to breast feed her on and off. She is taking formula for now, she usually doesn't have a problem latching to my breast but it seems like she is not getting enough milk cause she is hungry in the next 15 mins even when I do try to breast feed for almost an hour sometimes. I didn't pump yet because I don't think I have enough milk. Please help me, I really wanna breast feed her and start pumping but I have the double latch pump and it's really expensive and I don't wanna open it if I'm not going to be able to you use it... My doctor said it takes about 3 days for my milk to come in and I'm not really leaking or anything. Only a little bit comes out when I squeeze my breast and nipple. What should I do??
