Places like this, I think it depends on your server. You shouldn't ever assume that your under 3 child will get their own meals unless you are paying for it. In WDW right before covid, my youngest was under 3 when we went. At Artist Pointe Story Book Dining, he received a full meal just like his older 6 year old brother. However, at CRT when we went that same week our server told us that he would have to eat off our plates unless we wanted to pay full price for a second kid. We ended up having him share our food and his older brothers food. However, other tables sitting nearby us with under 3 kids got full meals without paying. I could overhear their server explaining this would be the case for them. Not sure why it varies so much, especially within one establishment---but just know to never expect getting anything for free. If you do---then consider it some pixie dust magic.
