Most of the TS places don't care (as long as it isn't pre-priced) and at CS they really don't care. That being said the CS portions for kids are mostly preschooler sized. We did a lot of sharing 2 adult meals among 2 adults and an 11 year old which worked pretty nicely. My 2 kids would often share 1 adult meal which was great as well. The sides on the kids meals are usually unsweetened applesauce, bags of carrots (good sized), grapes (tiny amount), or apple slices (small amount), or fries which were all fine but the protein part would be tiny--4 small chicken nuggets, tiny scoop of mac and cheese, 1 small chicken leg, or mini hot dog or small burger. They also have mini pizzas now too. My daughter was 8 on our last trip and weighed at most 60 lbs and it definitely wasn't enough food unless she filled up on fries or dessert. On that trip she and my 10 year were both fine ordering kids meals at TS and the amounts there were mostly ok for the younger one. RFC though may be a problem. It just varies but they seem to always try and pad the bill there and we were given a hard time when my son was 10 and 11 and my daughter at 9 (she's the size of a 7 or 8 year old). Ultimately they allowed it but it wasn't simple.
