My 3 yr old definitely does not have autism, but also exhibits a few of the items on that list. So I wouldn't worry too much. But if I were you, I'd print that list out and highlight what she DOES exhibit consistently and take this with you to the new dr. I think most Drs would have you change your child's diet first to see if any positive changes occur. I don't know much about it though.
Another idea too is to type your questions with space avail to write an answer. Hand the paper to your doctor and while you hold the two children in your arms, discuss the questions. If there's something you won't likely remember, ask the dr to write it down on your paper, ie: "What was the name of that brand of vitamin? Will you write that down under that question?" "What percentage was he weight? Will you write that down on the back for me?" If new dr has a great reputation, then it shouldn't be a problem.
Good luck!
