I can't help, but this is the question that keeps going round in my head too. We have a 20month gap, and money wise, plus for my sanity, we are probably going to wait until DD is 5 and at school, so that means our youngest, DS, will be 3. I'm worried that my 2 oldest will be close, and my youngest will be left out.

Hopefully someone with some experience can come in and give us a better idea
