how do i handle this? google. lol. i don't know all the answers to his questions(he is also 4 1/2). sometimes to quench his thirst i will buy him something with just lots of facts. he loves his leapster and loves this game called animal genius. it has so many random animal facts that he enjoys playing and memorizing, and then quizzing me, "did you know that......." to which i will honestly answer no most of the time. i do find when he has more to dive into and find knowledge on his own....he is less in the mood to ask me 57 new questions i can't answer in the car on the way home from the store. lol.
