Dd is 22 months and currently on a sleep strike of sorts. She used to sleep till 8/830 but within 2 weeks, she is now waking up at 6. Each day is getting earlier. Problem is, she's tired. When she wakes up, she wants to cuddle for a minimum of an hour. She also was falling asleep by 830 and now she won't fall asleep until 10 so in a month's time, she is losing nearly 4 hrs of sleep per day. She has blackout shades in her room already. Any suggestions?
