Agreed, but... Funnily enough, my 2 year old understands exactly why she shouldn't play in the street; Every time we go for a walk around the block and a car passes us, she tells us all "look out for that car, it might hit us!". And then again, I know plenty of other 2 year olds who can barely talk, let alone say something like that. And then I know 2 year olds who have dexterity and body awareness that makes my daughter look like she's walking around with a blindfold and her arms tied together. If being a parent has taught me anything, it's that kids are just incredibly different from each other. Oh, that, and that nothing good can ever come of a parenting thread on Hacker News ;) So many strongly held opinions from such small samples (often zero!).
