I sleep from about 9.30pm til 12.30am and im awake until 5.30am when I have to get up to go to work. I pretty much toss and turn (I probably drift off to sleep for about 15mins in an hour). Its not fun. My first pregnancy was the same and got worse as my due date approached. OB tells me its my body getting ready to be up at all hours of the night with the baby unfortunately my body has forgotten that I already have a child to tend to so this isnt really working out.
