Re: Sims Keep Having Boys

@AnneSims34 I'm not sure you're going to like this. :-/  In one game, the family had twins (the mother had the fertile trait); one girl and one boy.  In the next save, the family had a girl and then a boy.  So far, that seems fairly even.  I was curious about MCCC so I downloaded it.  I also have not been able to find the option to set offspring gender percentages.  On the computer, I only see an option for allowing male, female or both offspring and for setting the maximum number of offspring a sim can have.  As you mentioned, I saw options for gender and number while the mother was pregnant.  Now that the baby has come, the only available option is to start a pregnancy.  I don't see any pregnancy options from the mailbox either.  I did some research online but did not find any articles explaining how to set percentage for offspring gender. :-(

One post I thought was interesting suggested that the chance a baby will be male or female depends on the number of males and females that already exist in the game.  If this is true, then perhaps there is an abundance of females in your game so the system has been attempting to balance out the ratio by giving you male babies.  Perhaps if you use MCCC to increase the percentage of game generated males, you'll start having more female babies?  Or maybe decreasing the number of generated males means you'll have fewer male babies?  I haven't tested any of this and it's a bit confusing.  Anyway, if you want to try it out, I found the "MC Population" -> "Populating Settings" on a computer's MC Command Center menu. 

Edit: Sorry for making a long post longer but I was just thinking about the population issue.  I went to manage worlds and then manage households, to view the other households that exist in the game.  As of right now, I counted around 118 males and 122 females in my game (some I wasn't sure about based on appearance alone).  That is pretty even, so if that one post's theory is true, I might expect to have around 50% chance of having either a girl or boy, slanted towards male to balance the male-female ratio.  It might be a little time consuming, but maybe you could check the households in your game.  If there is a preponderance of females, perhaps that is why you're seeing more male babies.  One possible option might be to delete some of those female sims with whom your sims have no relationship or interaction.  This might increase the chance that your family will have more girls.  Again, this is just a theory but possibly explains the issue you're having.  It might be worth the effort as an alternative to using cheats and mods.
