I have a woman with blonde hair and a man with light brown hair, who just had a black-haired child. I think it detracts from the game to have the children not look like the parents; part of the fun of a multi-generation household is seeing various features passed down through the generations. I seem to remember that VF1 did this differently?

I had a person make a meal today, and as soon as he finished making the meal, the OTHER family members sat down and ate it, while HE went "looking for snacks." It seems sort of stupid for them to look for snacks when there's food on the table! I don't know how your AI works, but evidently this character doesn't know that he just made a meal...
