I keep repeating it because I like this quote from Little Man Tate, a quite well-made film featuring Jodie Foster as the mother of an exceptionally talented child that its teacher wants to send to therapy for being a misunderstood (by her) math genius, to which Jodie as the boy´s mother simply replies:
"Intelligence is not a disease!"
Sounds as if your children were perfectly normal kids (I worry more about those that don´t know how to play at all and can´t walk backwards since they never practise balance etc. through games) with perhaps a tad more phantasy and ideas than others provide. Your offspring may even have inherited this from their (ahem) parents. Glad to hear, you are not having a frog, next time!
