Hmm. Ds (two this week) is middling on this. I wouldn't have it at all if he broke other kids' toys, and if he did purposefully break one of his own - though don't think he has - there would be much ceremony to it going in the bin, to bring home the finality of it.
I can relate to both "sides" of this discussion. Ds has loved throwing since he was about 14 months, and he's bloody good at it. I don't want to stifle a natural skill, but it does mean endless reminding to throw soft balls (there's a box of these in the lounge for this very reason), as being a shade under two, ds's memory's failed him loads of times on what to throw.
And our remote controls have been tinkered with - ds's fascinated by the batteries, how they work, if they've run out, etc. And DVD cases do get opened and closed a bit forcefully. I believe a moderate amount of breakages and not-too-serious damage to things is normal and healthy: breaking things teaches kids something, and also kids have a lot of physical energy - some more than others - so to some extent it's inevitable.
This is another point: our son - his current habit of "angry" throwing aside - is just much more physical than his little friend who comes over a few times a week. They're the same age, but ds is bigger, more boisterous and throws further/whacks harder. Who knows how kids' levels of testosterone differ? You only have to look at adults to see how these differences remain - some are clumsy and uncoordinated and scatty by nature, some are like coiled springs with a lot of physical energy to expend, others are slight and gentle. I don't think this is all down to upbringing.
It's a balance. At the moment, we are finding ds a bit of a destruct-a-mobile - not in the damaging things sense, but in tipping it up if we've put it in, knocking it over if we've stood it up, etc. It's frustrating, but I think only so many no's are effective or wise. Loads of tellings-off stifle curiosity, which is one of kids' most valuable learning tools.
I reckon the ideal is putting valuable stuff out of the way and child-proofing as much as possible, not being too precious about the house (we're kitting out a whole house at the moment and have decided to go cheap and cheerful throughout until ds is older and can be expected, developmentally, to respect property), and saying no only when it really matters (not over remotes, for example). And it's a good plan to take them to places where they can do lots of rough, physical play.
All this said, ds has thrown a stone at dp's sports car, and drawn on the leather seats therein with a biro (a lovely rocket picture
) - but that's dp's problem for letting him play in there in the first place.
