My 3.5 Yrs old threw a bad tantrum, cried for 1.5hours and wouldn't drink or eat or change or talk. She even bite me, all because she couldn't wait for the bun to be heated up. I have already talk to her nicely that the food is cold and needs to be heated up if not she will get tummyache. How do I coax her if it happens the next time. Very scared she will throw tantrum when we r at some toy shops.
