So the first thing he signed was “I’m a girl”. When he was, what now, 2 or 3?

What if he got the sign wrong?

We live in an age of science, haha.

Ok, I’ll bite: what is the scientific evidence, the quantifiable empirical evidence, the laboratory tests, the evidence in the boy’s genes, that his DNA is wrong and his lesbian mothers are right?

I’ll take almost anything at all. Map his DNA and show me where the strand is that says, “Whoops! Should be a girl.”
