Pachyderm's wife, it sounds like I should clarify.
I don't want to hijack Minnesota's thread so I'll do the Cliff's notes version.

We were happy as a family of 3 and weren't doing anything to look for another child. We had often said it would be nice to have another one and that's as far as it went.

Got a call one day from an attorney I knew asking if we were interested in another child and things went from there.

She was born a month later and we got her at 4 days.
Our son was 11 months.
Hope this clarifies
