Since we already have a ton of baby gear from DD #1, we don't really need to buy anything this time around. The only exception is, since we're having a summer baby, I want to make sure we have a double stroller before DD #2 is born. Otherwise, I'm sure I'll get a lot of use out of our Moby, but we already have one.
Re: gear?
A carrier for the baby - I love our Moby wrap! The other two items that we used frequently were the infant car seat and the swing.
