I have massive nipples and all my babies have small mouths. Most of the time they get angry and just scream when I bring my boob anywhere near them. I've not had one successful feed with Mr. L. Its really frustrating. I'm so exhausted from pumping around the clock. So much so that last night I fell asleep feeding him and when I woke up I almost dropped him on the floor. I was so upset with myself that I decided not to pump overnight. I'm trying to only attach to my smaller nipple and if its successful I'll be happy. I'll probably give it another few weeks and then if its not happening he'll be moved onto formula like my girls. Its doing my head in.
