Our soon-to-be 4 year old has historically been a pretty good sleeper. We have a Tot Clock in her room and she understands the colors and follows the rules of the clock without much issue. That is, until recently. Bedtime has become a nightmare struggle of wills. Until about a week ago, my husband handled bedtime, went through their whole routine, snuggly tucked her in with her stuffed animals where she wants them, closed the door and she slept. Sometimes she would play quietly with her animals in bed before falling asleep. No issues. Now he can barely get out of her bedroom before she's out of bed, crying and ultimately screaming when she's not allowed to stay up, cuddle more, leave all lights on, etc. Bedtime has become an hour and a half of struggle and stress. A few weeks ago she started coming out of her room and we found that she would be fine as long as her door was left open a crack. Fast forward a couple weeks and now seemingly nothing will keep her in bed - soothing her, listening and validating her concerns, leaving the door cracked, closing the door, not tucking her in every time she gets out of bed, not repeating her routine, repeating her routine, taking stuffed animals away, putting a baby gate across her doorway (which was previously in the family room for years and she never figured out the lock, but five minutes in her doorway and she's now suddenly an expert locksmith). The only way she would go to sleep last night, after an hour struggle, was with her overhead lights on low. The process is exhausting for all of us and it's difficult to remain calm after several nights like this. We put the gate up because it was suggested by a few sources online and I couldn't handle my husband's threats of locking her in her room. She doesn't appear to be scared of anything specific but simply doesn't want to be alone. We've assured her that we are right across the hall or in the family room downstairs. I'm worried that we are causing childhood trauma by not knowing how to help her through this struggle. Any suggestions? Anyone been through something similar? Advice? Any and all help is appreciated!
