We found out with our son. And OH really wants to find out. He hates surprises. I thought it might be fun to try to wait, but I am ok with finding out too. Either way works for me!! We have NOTHING left from DS except his crib which the in-laws bought for us and it us beautiful, and we will have to buy everything new (or gently used!) anyway so that really isn't a factor. Most of what we had for him was hand-me-downs and second-hand and we passed it on to others when their time came. That and we have moved 5 times in the 6 years we have been together. That really makes you want to clean stuff out and not carry around things you aren't using right now.
This will be our last baby for sure, too. I didn't really celebrate my pregnancy with our son because we were so young and people were really apprehensive about it. This time I am going to do all the things I didn't do with DS.
