DS7 asks questions non stop and has since he started talking. It can be exhausting and I'm truly grateful for our library and google. As someone who considers herself reasonably intelligent it is rather humbling to try to keep up with him smile We've had to resort to digging out university textbooks to satisfy his interrogations on more than one occasion.

DD5 isn't tested so I don't know if she is gifted but she isn't like that at all. I often wonder if it is because she's been stuck listening to DS's questioning for years and either isn't interested or that she now has all the info (and more) that one could ever want after listening to our answers.
