Currently, with 1.6.3, I've found its hard to get wife pregnant after about age 22. I think it used to be age 25 that it became a very small fertility percentage. Not really a problem, just an observation. Also, my children have always seemed to grow normally. But 17 years of growing time before they are 'useable' is a long time in game. I'm curious whether the original posters had actual problems with babies not growing or were just impatient, or were just referring to the picture. I think Encyclopedia pictures update at a younger age than the clan page.
