Sims are only having sons

I've been playing the sims a good bit for the last week or two, and over three households I've had 10 kids. Every single one of them has been a son. Which is about a 1/1024 chance, or approximately 0.001%. After the first nine it was starting to feel really ridiculous, and I wanted one of them to have a daughter, so I had the mom eat a bunch of strawberries and listen to pop music in the hopes it would help. But she just gave birth to son #10.

One of my sims does have a daughter, but the mom of the child isn't part of the active household, so it might be a bit different.

I dunno. It might just be a really weird coincidence, I'm gonna keep having more kids, but if anyone has any ideas as to if there's something that got messed up, or a setting I could've screwed up somewhere, I'd appreciate any advice.
