Just thought I would post this to help and other mommies that have been as frustrated as I have been. My baby would get fussy so I had to constantly pump, warm it up, and feed baby. I felt like it was taking way more time than it had to. Then I realized I should try a nipple shield. Well I purchased one from Target and now he is BF with no problem! I wish I would have done this 2 weeks ago. But better late than never right. This is him sleeping after finally BF!
