This is a tough one. I don't think I would have done anything differently. I was very prepared for kids. I am the oldest sibling and cousin in a large extended family. I grew up having a new sibling or cousin every year or so. I am very used to babies and kids.

I guess for advice, make sure that you allow for time for you and your spouse to have adult time. You need time to date each other and appreciate one another. When kids are little they consume your whole life, which is how it should be, but don't forget to do things together without the kids. They'll be okay at grandparents for an evening, if you have that luxury. If not, find a trusted babysitter. It's healthy for parents and kids.
