So I guess there is some confusion about this, but:
One does not know whether one’s child is male or female or intersex until that child is born. If you get chromosomal testing (which is still quite rare), I suppose you can have a pretty good (although still not 100%) idea, and the ultrasound technicians will make a (sometimes very well informed) guess if you ask them to. But you don’t really know until the child is born.
So yeah, the reason I’m not talking about the sex is that the kid in question does not yet exist, and I feel weird about publicly assigning a sex to a person who is not even a person yet.
We are very excited to have another baby, though, so YAY regardless of whether the baby is male or female or neither.
