Anyone else a deep sleeper and dont remember shit in the mornings? Last night my son woke up at 1am and I fed him and put him back in his bed. I woke up around 5am I think and he was laying right next to me. I freaked out so I looked over me into his bed and it legit was my son laying next to me. It was only me and him so who tf put him in my bed? I don't remember getting up again and getting him and he deff doesn't know how to get out his bed.... Wondering if it was my mom but I doubt it she's all the way upstairs
