I think you should take things one step at a time. Don't stress about long-range decisions now. Do enjoy your Disney Wedding! It should be a magical time.
I'm in agreement with others who say that you should get out of your parents basement before trying to start a family. I'd hold on to both jobs or look for something more lucrative until you get a place of your own. After you move into your new place, you don't like working two jobs, then you can give up the bartending job. Hey, can't your hubby come hang out in the bar while you work? My husband would LOVE that.
I also think it's a good idea to have at least one child before you open an in-home day care. For one thing, to be a state licensed day care provider, your home has to meet all sorts of requirements. It might be hard to meet those requirements until you have a home of your own. You also might feel a little "cheated" if you are going to have to look after other children when you have a newborn, and I don't know how you can take a maternity leave from your in-home daycare. Maybe you can work at a day care facility to see if that is what you really want to do.
Most importantly, you need to be discussing with your husband when you want to have kids. I didn't have my first child until I was 37. You definitely don't need to wait that long, but I wish my husband and I had more time with just the two of us before we had kids. Living with either of our parents would have been hard on our marriage. The two of you need a place of your own.
