My kids are the form their own theory type. Mostly they are very logical but often wrong. Sometime I can see where they went wrong as in "i can see how you got there but you were missing a piece of information", sometimes they were funny - hatchbacks have windscreen wipers at the back because they go both ways like those double ended trains. Ds4 asks a lot of "what does 'word' mean questions. But like a lot here i talk to my kids and read to them and don't dumb down or assume they don't understand.
