This question made me laugh! Our children are somewhat widely spaced due to how exhausting child #1 was. Also, we're not having any more, but that's also a function of house size and financial carrying capacity. My two kids are SO different in personality that I do sometimes feel a twinge of sadness that there won't be a third, just to see what the mix would be.

I do sometimes wish I'd had them closer (they are 4ish years apart) but given how things were, it's okay. They act closer in age than they are, with my oldest acting young for age (emotionally) and my youngest acting old for age. I think this often happens.
