My 7 month old DD is a nightmare at bedtime. She wakes up every 10 mins from 7:30-10:30ish. She has done this for 4 months now. We have tried everything. Longer/shorter wake windows, more day sleep, less day sleep, earlier/later bed time. Nothing makes any difference. I don't know why she does it or how to make it stop. She has all of her naps in her room, and she sleeps soundly, its only bed time.
