welcome to the board
My DD's aren't HUGELY spaced, but there is 3 1/2 years... I'm a single Mum & part of why I had my tubes tied is that I don't want to go through 'all of this' (ie the baby stuff) in a few years time when I have older kids.
THAT said, if I didn't have baby #2 yet, I would most certainly be looking to have more children when I eventually found 'mr right'. I do understand where you're coming from!
