I am going through a very weird stage with sleep. DS is 5 and a bit months, so it's been pretty broken, but recently I have developed a weird habit.
In the middle of the night when I am fast asleep for some reason I decide that DH is DS. (We have never ever co-slept so I don't know why my subconscious has decided this).
Sometimes I scrabble round under the blankets worried that "DS" is stuck under there. The other night DH found me pawing gently at him - I was confused as to why "DS" wasn't wearing the merino onesie I knew I'd put him to bed in. And last night DH awoke to me insistently trying to turn him on his back! (Which he resisted - in my subconscious state I couldn't figure out why 16 pound DS was so unwieldy!).
DS is not even in our room any more! He's safely tucked up in his own cot. I've occasionally sleep talked before but this is a bit spesh. DH initially thought I was getting a bit amorous until he realised I was in my own universe...
