HELP!

OKay, so it is 12:39 and I am still awake! I am having a very hard time getting Landry to bed. The thing is, she is wonderful ALL Day and early evening, but starting at 10:30...ahem, bedtime!...she turns into something else. We usually keep her awake from 7:30 to 10:30 and then we all go to bed. Correction - JR and Logan go to bed, Landry and I are up until around 2..she sleeps for about 3-4 hours, sometimes 5 on awesome nights! She eats and goes right back to sleep. She does this until about 11 - 11:30. So my idea is to try to keep her awake after her 9:00 feeding...which is when I usually spend my cuddle time with Logan and I am very skeptical about moving this. This is designated "Logan" time! But I dont know what to do. It seems like she just has to have this crying period but....and I swear...she can be totally fine in the dark in the living room, but the minute I take her to the bedroom and lay down the screaming starts! IT is driving me crazy...I want to go to bed with the rest of my family! I have read two books since Friday...I am running out of things to keep me awake.
