What do I do?

Okay so long story short my husband works nights and so I’ve gotten in the bad habit of just going and falling asleep with my 4 year old in her bed. She has to have someone lay with her and hold her for her to fall asleep and I’ve tried a few times to make her sleep in her own room/bed but she ends up waking up and realizing I’m not there anymore and freaks out so it was just easier to sleep with her. I need advice on how to make her feel safe when she wakes up and I’m not there (bc I need to sleep in own bed with husband) and help her stay asleep through the night (she doesn’t want anything when she wakes up just for me to hold her back to sleep) She has a night light and a tv in there so it’s not dark. I leave both doors open and the bathroom light on too. What have you guys done to help your little sleep in their own room?? Help please 🥲

P.S- I know I did this myself but I just wanted sleep and to make sure she got some sleep too.
