I agree that you have to make YOU a priority too. As Mom's, we put "us" at the bottom of the list. However, if you were the CEO of a company, and you saw your key, right hand person running themselves ragged, you'd force them to take time to recharge. Since you ARE the CEO of your life, you need to force yourself to invest in you. Schedule yourself something once a week where you know that this time is for YOU. Stroll around a mall, go for a walk through a park, treat yourself to an ice cream.
I agree that going to a hair dresser to give you a "wash n wear" style would be best. Maybe scrinch it with a bit of product and go. A girl friend and I also spent an afternoon once with a makeup artist to teach us about our makeup. She reviewed our makeup bags, told us what was good, what wasn't, how to apply it for the best effect. She also taught us a "quick day look" which was under 3 minutes and how to "vamp it up for night" which was an additional 5 minutes. It was a GREAT afternoon and really helped me to know that if I set up LO for 3 minutes in her exersaucer with some nutrio's, I had time to make myself look human.
