My 4 yr old dd came out of her bedroom to tell me 'it's 9 o'clock time for bed.' It was 9:15pm. I asked her how she knew it was 9 o'clock. She told me a voice through the wall told her it was 9 o'clock go to bed. Sometimes, dd can't get to sleep and chats to her dolls while lying in bed. Sometimes she gets up multiple times and comes into the lounge room and I have to take her back to bed. Many times she comes into my bedroom and co-sleeps. Lots of children go through stages like this so I'm not worried about that. I am worried that someone I don't really know thinks it's ok to talk to my daughter through her bedroom wall. Aibu to be concerned about this?
