I couldn't sleep at night (at the mo) with the window open, and I live in the warm south! (but I am also a southern softie!
- I wear socks in bed almost all year round!)
My hairdresser told me off for washing my hair every day & challenged me to only do it every other day. It only took a week or two for my hair to adjust & I now only wash it every 2-3 days! I also wash it at night as no time to do it in the mornings! When I was at work I would also style (straighten) it at night, which sounds crazy, but it would only need a really quick re-straighten (on the side I sleep on) in the morning!
I don't know what midwife prog you are talking about, but I sounds like something I would cry at (I cried during the introduction to OBEM!) All DC are very precious gifts, I must remember that when DD2 wakes me in the night!!
