Quinn's new thing is to throw, throw, throw EVERYTHING — his toys, his food, pretty much anything he can get his hands on. He laughs hysterically when he does it (which is quite charming) and I don't want to squelch his fun, but it can get fairly obnoxious when he throws food in restaurants or toys at the dogs (one of which is quite terrified by objects flying at her and spent much of today outside despite the heat).
Please tell me this is a normal stage of development. And assuming it is, how long does it last? And until then, how do you discourage the behavior without discouraging the kid?
