Totally agree with Grace! ME time and US time is very important for maintaining the mommies' sanity, and the spark in our relationship! Not too long ago, DH and I took half day off - started with a buffet, and then watched a movie. So nice! And even more recently, we tricked the kids to sleep at 8pm then left the maid in charge, and we went out for a 9pm show.
On a daily basis, it is important to prioritise, and try not to be that super woman! I subscribe to Gina Ford's routine for the children, waking up early and going to bed early 7 - 8pm. This works very well, because we could either have an early dinner with them, or have a late dinner without them. Once they are in bed, the house is in peace and we can do some cleaning, washing, or things like watching the news, reading, or catching up on work emails.
