We just came back last week and were on the dining plan with a 9 and 2 year old. (So my 2 year old didn't get any credits and was expected to share) My DH never eats dessert, so our waiter always offered to bring a second kids dessert for my 2 year old in place of DH's dessert. We only took them up on it a few times (since we really didn't want to overdo the sugar anyway) but they all seemed perfectly willing to substitute a kids dessert for an adult credit.
