My LO has been acting weird the last 2 days. I think she's teething. She's been putting herself into overtired mode and taking a long time to fall asleep. Yesterdays nap ended up from 1-3pm when she should of been sleeping by 11pm. I put her in bed at 7pm and it took her until almost 9pm to fall asleep. Although she did do it on her own. This has happened many of times and it always goes away and she goes back to normal.
I think I did a smart thing this morning though. She woke at 6am and I was going to let her stay up until closer to 11am, but at 10:20am....she was acting tired and I just knew she's getting herself into this cycle of poor sleep. So I took her upstairs and put her in the crib and said good night. She was sleeping within 15 minutes or so. It's 12:34pm and she's still sleeping. She'll probably wake soon. actuallY might even hear her now.
Maybe ONE night, put her to bed extra early. If she's been in overtired mode...she might need one EARLY night. My doctors says NOT every baby sleeps a lot. Some just sleep less than others. My Lo normally sleeps a good 10-11 hours at night...if she's doing good and a good 2 hours during the day.
I don't know if I directly answered any questions, but hopefully some of my experience helps you a little.
