Sims 3

I seriously need help. it's a problem in my sims 3 legacy challenge- it's supossed to be female dominated, but instead my female sim got stupid male children! there needs are static, and this is a second twinbrook save file after the old one that is so horridly corrupted. it may be a glitch or something, and i wonder if i have to make needs dynamic so that I can get female children. It's a really horrible problem, and is there a way you can cheat the gender of the child? It's not that i have something against men- if there's a female founder for the challenge, then it has to be female dominant, right?
