It seems to me that there have been fewer (possibly no) townie infants born since I got Pets, except to mothers who are already pregnant at the beginning of the game. Before Pets, I had two heirs in a decadynasty marry the younger children or descendants of townies, but after Pets, it has seemed as if the only children are newspaper deliverers or ones who have recently moved in. Has anyone else noticed this, or is it just my computer?
