Dear Mumsnetters. My 17mo DS throws everything, and I mean everything - his lunch, his toys, anything he finds... especially fun are the vegetables from his dinner plate. I've tried saying no, being stern, removing the items as soon as he's thrown them, all the usual stuff but he smiles on and continues regardless. He's been doing this for about 4 months. Should I be trying something else, being much stricter, or just let it pass as a very long annoying phase?! If he's completely ignoring 'no' now for something like this, I am filled with terror about the coming 2 years! Any advice very welcome.
