Every morning, take a shower and put on some makeup.
Brilliant! When you're frumpy, post-baby-weight, sleep-deprived body meets real life, it makes all the difference in the world to look and smell presentable. There may be days you accomplish little else in those first couple of weeks home from the hospital, but your whole frame of mind is much more positive when you're clean and not embarrassed to be seen! Did I mention that Mrs. Troop has EIGHT children. She might know what she's talking about! :)
It's not so important that you look good while you're changing diapers and wiping bottoms and printing Batman coloring pages and disciplining the other children and feeding the baby and feeding the other kids and loading the dishwasher and folding the laundry and refereeing disagreements and finding Hans Solo in the pocket of the other shorts ... it just makes you feel better. No, I don't have it all together and never will - but I'm clean!
