So recommendation, depending on what your end goal is here, but maybe you should hide stats on children until they grow up.
It is really weird to see a newborn baby with a fertility rating of Fecund.
FYI, Fecund means basically extremely fertile, and is normally used with reference to livestock like cows to describe that they have a lot of babies.
*edit... actually having played, don't just hide stats, have them not even calculate until they reach adulthood. The reason... fertility decreases constantly throughout life, which isn't correct, it actually increases to a point and then decreases, but in game since fertility is applied at birth and then constantly decreases, it makes it so that most of the children after reaching adulthood only have a couple years that they can get pregnant, by the time they are like 25, it is basically impossible.
