DP and I are in the talking about having DC stage and I can't come up with a single logical reason to ttc. DP can't either and said he "just knows he wants (more) DC" - he already has a 5 year old from his first marriage. I know I want DC but then if I think about it logically I just think about how much less money we'll have, how much harder it is to travel, have date nights (we have little in the way of family support for babysitting), sleep in etc.
It just made me wonder, what made you actually decide to go for it?
