DS is now 15 months old, and while he doesn't often throw things, sometimes he'll throw something either out of boredom, frustration or annoyance (well, those are the emotions that I perceive he is feeling at the time...). Because it doesn't happen often (he's never been a big "thrower", and never even got in the habit of throwing food off the highchair which I know a lot of children do) I generally just tend to tell him "Uh uh! No throwing!" in a stern voice and take the toy away.

I took him to a new playgroup this week and it's a lot more strict than his old playgroup because the new one is a Montessori group. He's the youngest in the group, so I don't expect him to behave exactly like all the other kids. At one point he was playing with a toy that was basically little wooden colored rings that you stack on the matching colored sticks. He was playing nicely with it, but then started throwing the rings instead. Of course the annoying little things had to roll away as well, so it made it more obvious that I was chasing thrown objects, lol. I told him "Uh uh! No throwing!" as usual and I tried taking the rings away from him and giving them to him one at a time. But he'd put a couple on the sticks and then start pulling them off and throwing them again. In the end I took them off him and put the toy away, but of course he got upset by that and started what I knew were the beginnings of a tanty. Because I know they like to keep a calm, peaceful environment there, I scooped him up and took him to get a new toy, but I wasn't sure if I was just rewarding bad behaviour...

What would be the "right" thing to do in this sort of situation? I obviously want to teach DS that throwing is not acceptable, but I guess I'm also worried about looking "bad" or being embarrassed in front of the other parents when their children seem to be playing and working so nicely.
