There is like no way DH would agree to a third child.. but still, I'm curious. I guess one of the big things is stuff like carseats in the car. If you have 3 kids, does that mean you have to get a huge vehicle like a minivan? I have a Hyundai Santa Fe, I can sit between the kids seats in the back but it is a super tight squeeze, I don't see an infant seat back there. I mean we'd have most of what we need for another kid, but if we had to get a new car then it would be a whole different ballpark.
