And, while I am here, I never knew about the meltdowns as the tablet wears off. Wow! They are pretty extreme. My son was hyperventilating whilst telling me his heart was broken because he missed out on a ride at the xmas party. I dont think I have seen him so upset before! It only lasted 10 to 15 minutes, but it was pretty extreme.
