I know for me it took a while to get into a routine pumping so my body would produce more. Babys are very good at nursing and the pump doesn't mimic that very well. Don't give up pumping if you want to provide breastmilk for your baby. But also don't feel like you've let anyone down by suplementing with formula. Your baby is so lucky to have you giving her the best you possibly can and while I know giving her formula may seem like a big deal now, it's only one of many tough decisions we as parents will have to make! ;-) Good luck and don't be too hard on yourself! You're amazing to be working and pumping, it's very difficult!!
