My friend has 3 boys age 4,2,and 8 months, the middle child being the only one who suffers from allergies. He is now at the age where he is asking for the same food as his brothers, but not old enough to fully understand the consequences of eating them. My friend is wondering whether it would be fairer to make the rest of the family follow his diet or does he just have to accept that he can't have all those tempting foods? Is there anyone who can advise please?
