21 month old sleep regression?

Help!

Ok, so firstly we have had some BIG transitions that do associate with the issues: - We moved about two months ago - With the move, transitioned to a toddler bed (from a crib) mostly because I thought she was ready, not because she was climbing out

Since the move, I have struggled with first, early morning wakeups (5am) and in the past week she’s started waking up in the middle of the night. She is screaming with panic and banging at the door. I have walked in, without a word, and she’ll go to bed, but then jumps up again as soon as I leave. We’ve been staying with her to go to bed (at bedtime) until she’s asleep.

General sleep schedule:

• Bedtime around 7pm, wakes up usually around 5am, with at least one wake-up in the middle of the night (usually lasting about an hour of repeats of me going in, putting her in bed, and walking out)
• Naptime is around 11, usually no more than 1.5 hours; if we skip naptime she’s exhausted and barely making it to the 7pm bedtime.

Any thoughts? I don’t think a toddler wake clock would work because she essentially wakes up in a panic. I’ve tried to put her in the pack-n-play we have and she refuses to be in that but we may try to transition to that as well.
