Update

Well I wouldn't call it a complete failure but it wasn't exactly a smashing success either. I put Z to bed last night at 6:15 and at 5:30 she made a few squeaks and then was quiet again until 6. The one major improvement was when I went to get her at 6 this morning she was happy and not the usual grumpy pants that she usually is. She did get about 2.5 more hours of sleep last night then she usually does so that's a bonus. She's in bed already tonight and it's now 6:30. Let's see how tomorrow morning goes.
