Survey Questions at 4 Years Old

I asked Sam and Anna these 21 questions at 2 and a half years old and 3 years old.  I also asked the same questions around their 4th birthday last March.  My plan is to ask the same questions every birthday from now on and see how the answers change.  Answers in black were what was said at 2 1/2, answers in blue are what Sam and Anna told me when I asked them the same questions on their 3rd birthday.  The red anwers are what was said at 4 years old:
