I believe there is no charge at any of the family style and buffet meals for under 3's. My youngest is now 7, but for years we did not pay anything at the many character meals, including CRT, for anyone under 3. They will either bring out a smaller meal if it's a toddler (vs an infant who obviously isn't eating) or any empty plate for others to share. And since you can get more of anything, it's no big deal to share...
Hope that helps.
