First off, I've been in the Army for over 10 years. I am a woman. I say that because it's important for you to understand that not every soldier or sailor is male. Some soldiers and sailors have husbands waiting back at home. I know this is contrary to the stereotype, but that's the way it is. You asked for advice from "navy wives" about the lifestyle; the term you'll want to get used to if you're going to be a military family is "military spouse."
Yes, you do move around. As a married family, you'll move every 3 years or so. You'll get used to it...and your husband can apply to stay where you are for another tour of duty should your family have a need to stay, or decide you like where you're at. Consecutive tours are not uncommon.
Schooling depends upon whether you live on base or not. Department of Defense schools are incredibly good, and they are well-versed in the needs of military families. They will work hard to ensure that kids transition comfortably and easily. For the most part, schools near a base also work well with military families. Most of the kids who attend there are military kids and so they know what to do. This isn't their first rodeo, and your kid will be one of many navy brats. :-)
The military is hard on families. So if you don't already have a very strong marriage, it's not for your family. Divorce rates are significantly higher for military families, and a lot of time and care is required to ensure that your family stays tight. I cannot stress this enough. Deployments are no joke. If your family struggles when your husband is gone for a week, consider that he will be gone for months at a time. You will basically be a single parent. The military does provide a lot of resources, but for the most part, everyone is in the same situation. You have to be willing to make friends and lean on one another while your spouses are gone. You have to trust that your husband will remain faithful, and he has to trust you will too.
I have loved my military career. I'm a medic. Be sure your husband picks a job he can use on the civilian side. That's important. Also, be sure you both pursue your degrees. The military pays for his education, and there are TONS of online and on-ground colleges out there that will pay for yours too, if your husband takes classes with them.
Best of luck to you.
