Anyone else has a Monster who destroys their own toys? My little Monster is 1 and just destroyed her toy piano!

My son is 2 years old, and born like an explorative engineer. He tries to play each toy he has "normally" for a while, then starts trying to analyse the nuts and bolts before pulling things apart! I hardly buy any toys for him, mostly secondhand ones given by other people - but when I do I make sure it's safe enough for his engineering soul :x
