Baby Talk

I baby talk with my husband all the time (sorry to those of you who happen to hear it all the time... haha).  I've been thinking about what would happen when we have kids.  Would we still baby talk to each other?  Is this just a phase in our marriage?  I admit, it is a weird thing we do.  I don't know why we do it, but I'm pretty sure I got it from Robert haha.  He would talk like that while we were dating and I just sorta started doing it.  You really do become the people you hang out with the most.  Anyways, I hope it's just a phase... that would be strange hearing 40 year old parents with teenagers still talking to each other like they were babies.
