Zahavasdad: I used to dislike the taste of meat intensely. My father told me I had to take at least a little cholent because it was the only hot dish on the table, in order to be mekayem the mitzva of the seuda in the best way.
I ate about a teaspoonful of cholent every Shabbos, didn’t feel forced, and over time began to tolerate and even enjoy it. Now I eat a regular serving of cholent most of the time.
The men here can tell us about the halachos involved, but chinuch wise, not eating a major dish is going to be problematic for a child later on. Forcing a child to eat it is obviously not very helpful, but having them take even a little bit, just to be part of it, is very reasonable.
