sleeping - night #3

I'm not sure the "tank her up" thing works so well for Judith. Maybe her little stomach just isn't ready for that much food? She gets really gassy and spits up a lot after the last feeding of the day. Last night was pretty bad - lots of screaming and buckets of spit - and it took her almost two hours to go to sleep! She was finally asleep around midnight. She didn't wake up at 4:00; she slept straight until 5:30, which means that she did go 7 1/2 hours without eating, but she was only asleep for about 5 1/2 of those hours, so I wouldn't really consider it sleeping through the night...but I guess it's another step in the process. She seemed pretty hungry at 5:30, but she fell asleep eating again, and only ate for 10 minutes. It's extremely difficult to wake her when she does that, and I'm getting a little wary of trying to "force" her to eat more, because it just seems to make her spit up. I'm really not sure what to do about that!
