How to deal with

I also experienced the same thing. I understand how frustrating it feels. What did I do is I just change rice to other things that give similar nutrients such as oat, pasta, mashed potato, or bread. Mum, you can also try variety of recipes for your kids. And sometimes, I do did some "cheat" whereas I add some rice in her mash potato bowl and he just eat like nothing bother him. My son is also 3 years old. But still I tried giving him rice with ketchup sauce sometimes (of course with fried fish or chicken) to test try and error and gladly now he eat it! 😃
