One of the things that Alex and I try to do on a semi-regular basis is go out on dates. Sometime, somewhere, I read that going out with your spouse once a week allowed you to continue to grow and build your relationship, especially once your children are born. That way, when your children are grown and out of the house, you are not sitting across from a complete stranger. Well, we certainly don't make it out once a week, but I think we do pretty good at least going once a month.
Changing how I "do Mom", one little step at a time.
