My daughter is 26 months.. when I make her sit to eat on her high chair.. she has the habit to throw things down suddenly. Like shez having her lunch and than as if she gets irritated or angry and just throws things down.. why do they do that.. I explain very nicely that she should not throw it down. She says ok but repeats it as if she does not want it anymore.. or she gets irritated. Can u suggest what should I do and how to handle it.. thanks
