Advice for first time mommies!

I've been noticing that a lot of women who are in their first pregnancies are having a lot of questions and worries, much like myself. I know that not a lot can make me feel better or stop me from stressing but women who have been through this and give me much needed advice always seems to calm me down. So I was wondering if you experienced mommies could give us mommies to be some advice for our pregnancies and for after the baby is born. It would be so greatly appreciated!!
