Long Night

I'm working on getting Ainsley to sleep all night (or at least 8 hours) without waking up for a feeding. For about a week now she has only been eating an ounce or so at her nighttime feeding, so according to the pediatrician and the sleep book that means she's ready to start sleeping through the night. When she wakes up and wants to eat I'm supposed to let her try to calm herself down and get back to sleep and if that doesn't happen in 5 or 10 minutes then I can go in there and comfort her but not pick her up unless she's really upset. I wasn't planning on starting this until the weekend but last night she lasted until 4 a.m. so I figured why not go ahead with the plan since it was only going to be one more hour until it was time to feed her anyway. It ended up being much harder than I thought. She was fussing a lot and I waited outside her room (by waited I mean sat in the floor and cried) for nearly 10 minutes and then I couldn't stand it anymore so I went in to "comfort her". I think that me being in there just made it worse and confused her more and I ended up picking her up because she was crying really hard. Now, at 8 weeks she already weighs 13 pounds so I know logically that she is not going to waste away overnight, but I felt so bad because I knew she just wanted to eat and I wasn't letting her. She calmed down some when I picked her up so I put her back down and patted her some more. She stopped fussing around 4:45 and I could hear her sucking on her hands (she hasn't mastered the thumb yet) and I went back in at 4:55 so I could change her diaper before I fed her at 5. She seems fine today so I guess she wasn't too traumatized by the whole thing. I'm already dreading doing it again tonight. It's supposed to only take a few days for them to adjust their schedule and sleep through the nighttime feeding. I've got my fingers crossed!
