It's getting lighter and lighter these days, and my 18 mo old isn't falling asleep until 8:45. We have to get up early, so that really doesn't give me any adult time, as I have to head to bed not too long after that. I suspect that it's the light. She has blinds and curtains on her windows, but they both let in a lot of light. She doesn't nurse to sleep anymore, so after she's done nursing I feel like I'm held hostage until she falls asleep. She's wired! Talk, talk, talk. If she's on my lap she pounds her heels into my legs. If she's on my shoulder she tugs at my hair. If I put her in her crib she's up, she's turning circles, she's kicking the sides. She's in a good mood the entire time, unless I ask my husband to trade places with me. Then she gets very upset. I'd consider moving bedtime back a bit (though not happily) except that she usually has a total meltdown when she's ready to nurse - which could be anywhere from 7:30 - 8:00 - and she won't let me delay nursing at all. Plus, her older sister's a morning grouch, and doesn't fall asleep herself until 9ish. I don't want to move her bedtime too.
Did you notice that light affected your kiddo?
Did you ever try blackout curtains?
Is this just a phase? (It's been going on for about two weeks.)
