Probably should have posted in mods, nevermind. You need to edit a file called wifes.txt inside ses.kfs which can be opened with winrar. To eliminate children you need to use the command console in the game and use "clearwife" this will delete your children. In wifes.txt for each wife there is a pool of children that each wife can potentially give birth to. To choose children you want, edit each wives pool accordingly.
