8 month old napping/sleep problems

Sa

Hi all! The little girl I nanny is having a lot of trouble sleeping. She will not stay asleep for more than 45 minutes. I have tried gently almost waking her up just before 45 minutes and soothing her back to slee to help her transition sleep cycles, but it’s not working. She just wakes up a few minutes later. When I pick her up, she’ll start snuggling up and wanting to fall back asleep. We’ll go through her usual routine and then I put her down in her crib while she’s still half awake (she’s pretty good at putting herself to sleep) but then she just starts SCREAMING. Sometimes she won’t go back to sleep and other times she clearly needs to go back to sleep, but will only do so if I am rocking her. And I mean I can’t stop rocking her. The moment I stop rocking, she wakes up and SCREAMS.

This morning her dad told me that she did not sleep well at night over the weekend at all. He said she was basically just taking naps all day and then naps at night.

She did just get her first 2 teeth, but she’s having no other issues other than sleeping now and the sleeping seems to be getting worse.

Any tips??
