Re: No female child sim townies
Just to clarify, have you been looking specifically looking for female child townies or is this more so a comment about how there is not a lot of them?
Overall, the total number of female child townies will depend on which expansions/packs that you have, and which worlds you play in. I find some worlds do not have a lot of children walking around (Forgotten Hollow for example), whereas others have more (Willow Creek for example). I've also found that if my sims family has a child sim in it then other child townies are around more.
There are currently around 15 child townies in the Sims 4, with 7 of them being girls. If you have been actively looking and are not seeing any I would have sim move into the same neighbourhood as a family that has a girl child and see if they actually leave the house/even exist in your game. Or you could play on a lot near a playground to test if any child sims walk by.
Here is a list of all the kids in the Sims 4 based on world and game expansion/pack (I'm pretty sure I got all of them) for reference:
