Well, my youngest is 2. My oldest has a 18 year old and he (the 18 year old) is living with us too. The 2 year old eats what we eat. The 18 year old either eats what we have or he can make his own. I don't care as long as my wife doesn't have to fix double meals for him. Unfortunately, my daughter in law is the cause of the 18 year old not wanting to eat much. She is super picky and will horde food and not let anyone eat it except for her. Needless to say she has created two children who are the pickiest teenagers I have ever seen.
