Dd hs been sleeping with me and dp since the day she came home from the hosptial, and is now 5 months old. the past two nights, I've woken up with my back to her! It's totally startled me, and I'm wondering if it is something that should concern me. does it mean I'm tuning out? has anyone experienced this? I'm afraid that if my back is to her, I won't wake up when she needs me to.
