When my son was tiny tiny it was a time of survival! No sleep constant breastfeeding and diaper changing and running to the bathroom when I found 5 seconds. NOW he is 7.5 months and it's much easier of course and I started to stay up till 10 10:30 and he is up in the middle of the night (2times) to eat and I breastfeed. AND last night I went to bed at 845, and now feel like a new HUMAN BEING! I got 500% more stuff done than usual before 830am! Moral of the story? Choose SLEEP always. And save a late night for date night or once in awhile Housewives of "" binge :)
