Taking Cara Babies ABCs of sleep- 5m old sleep help!!

I’m at a loss of what to try anymore. My 23 week old daughter won’t nap for me. She sleeps at the most 40 minutes each nap and as a result is crabby all day.

Nighttime sleep isn’t great either. We just purchased the takingcarababies ABCs of sleep class and tonight will be night 3. I know it will take her a while to get it figured out but she’s very strong willed and won’t give up and go to sleep.

She can put herself to sleep so easily for both naps and bedtime. Staying asleep and transitioning from one sleep cycle to the next is the hard part.

We do one feeding during the night still and even then she doesn’t always finish her bottle so I feel she really doesn’t need it. Part do the sleep class is weaning night feedings as well.

I know she’s ready to sleep train. She so smart but too stubborn. I’m exhausted, she is too but won’t nap of course. I’m starting to go crazy. I don’t feel like myself and I don’t get much help from my husband. Anybody ever take the ABCs of sleep class and have success but it took them a while? Looking for some weigh in on the subject.
