I found that if I slept with DD she would usually drift back to sleep for 40min-1hr sometimes, or she'd just play by herself, but we were still up by 6ish. Now she's decided 5am is a good time to get up and I'm NOT happy!! I thought 6 was early...
I tied putting her to bed later but it never worked it just meant that I got less quiet time at the end of the day and she was overtired cause she got less sleep.
