It just strikes me as an odd thing to bang on about.
"Oooh! One of each, aren't you clever!"
Ummm, no. It wasn't anything I did, and I would have been just as thrilled if DC2 had been another girl.
If he had been a girl would everyone have been secretly disappointed? Would they have assumed I was disappointed?
What about families who have all girls or all boys? Have they failed in some way?
And what is the deal with assuming that now I've got "one of each" I won't be having any more children?
