Sims having all boy babies?

Thanks I feel better about it now. Someone posted there babies from a completed 100 baby challenge. Ya'll may have seen that post. The person who posted listed all 100 babies with names and gender and her's were pretty evened out. She didn't seem to have streaks of a bunch boys then a bunch of girls. I'm so jealous. Lol. I was beginning to think something was wrong with my game but it seems this is pretty normal. Thanks again.

Edit: Oh @SimAlexandria that post was yours lol. I looked again and did see streaks of girl or boy in your game. I feel better now! Thanks!
