You are super lucky to be a girl dad. It takes a special guy to make it through those girl teenage years!
When my two daughters were young we would get asked all the time when we were going to try for a boy, as if that’s the prize everyone should aim for in life!
We did end up having a third and he was a boy but now we get all these questions and assumptions about his sporting abilities and he is a kid who has no interest in sports whatsoever.
It all boils down to the fact that people are annoying and have nothing interesting to say so they say the stupidest comments!
