Right now we have two kids. A 2 year old daughter and a 4 month old son. I love my family of 4, but I keep thinking of maybe adding one more. DH is on board with 3 if I want, but says it's ultimately up to me since I stay at home with them all day. Let's talk pros and cons?

Pros:
Another baby!!

Cons:
I feel like the world is set up for families of 4:
4 people fit comfortably in a car
Family vacation packages are set up two adults with two kids

Being pregnant again (I suck at being pregnant)

Hmmmm....can't think of much else. Anyone else considering a 3rd baby?
