Sleep Sleep Sleep

So my 20 month old was doing so well with sleep training. We started at 12 months and she was doing a great job. She was sleeping from 7:30-5:30 and then I’d let her sleep until 7/7:30 in my bed. Ever since we went on vacation a few months ago, her sleeping has been so off. I also recently stopped nursing her to sleep and now she needs to feel some part of me, so she screams in her crib until I pick her up.

My questions:

Does your toddler fall asleep independently?

What times are they sleeping?

Is your toddler staying in their crib/bed if they wake up too early?
