Aw, I'm sorry Sweetie. It's really hard when they go together that way. Your kid at home will leave for college between the age of 18 and 19 Sweetheart. You can wait for him to leave or start a new generation by hitting the new generation button in the family screen. I've rarely ever started one before all family members have left the house empty, though there is nothing wrong with doing it.

I get attached to mine too. I think it makes us take care of them better.
