Broom, it took me 5 years to get #2!
Now I have my 2nd DD and am done.
I have to say though, I would have liked them a bit closer together, but am loving the age gap now, I get to spend dedicated time (and rest) with baby when DD is at school - and the eldest is fairly self sufficient, which means I don't feel 'guilty' for not being able to do certain things for her right away. She isn't as demanding as a toddler, loves her sister and realises babies can't do anything for themselves and sometimes she has to wait. :-)
