Help 👋🏻 6 year old will not stay in bed 🛌

5 months prego and the last 3 weeks my daughter will not stay in her own bed, keeps saying “she wants me”not that she’s scared or anything else. Bought her a new night light, sleeps with a diffuser, no matter what she wakes up in the middle of the night to climb in bed with me. I’ve took her back to bed until she falls asleep and she keeps coming back. If I let her crawl in bed with me she is out cold all night. I don’t know what to do, I’ve heard stuff like this gets worse the closer it is to baby getting here...any suggestions??
