Pros/con's

Pros of having another baby:

I make really, really cute humans
I have some awesome names
I love babies.
I want another one
We already have a minivan
We have the bedroom space

Cons to having another baby:

We'd be outnumbered
Financial setbacks
Delay me going back to work or school by another 3 years or so
What if it's twins?
We'd lose our spare bedroom
I've been getting rid of baby clothes
We already have a boy and a girl - zero population growth (pro?)
The current baby is still not sleeping through the night
