At three weeks of being a mother, I have 2 key points to share.
1. Pregnancy is the easy part of parenting, Swollen feet, getting up 3 times a night to pee, waddling all over the place, and all. At least while pregnant you are still responsible only for yourself.
2. The secret to feeling half way decent when you have a newborn at home is putting on earrings that you can wear around the clock. That way, when you glance at yourself in the mirror (in passing... usually just when washing your hands) you feel like you have a tiny part of your life in order. Even if it's your ears.
