My 15 month LO has been driving us crazy with 5:15 am wakeups. She goes to bed at 7:30..we have tried moving it up and back to see whether that had any effect on wakeup time, but with no success.

I have been holding out for her daycare transition to one nap, which is happening next week. My hope is that after she transitions, she will stretch out her nighttime sleep a little longer ... an hour would be glorious!

Anyone have success with this? Or remember what happened to nighttime sleep after transition to one nap?
