Thanks for the insight. DS is sometimes fearless and sometimes a scaredy cat. If he's overdue for a nap, he'll tend to be more afraid and cry easier. I plan to keep to our schedule here at home. I certainly WON'T overdue it like I see so many parents do.
He doesn't like me to "put" him on anything. Like at the zoo, if I put him down next to a statue or on top of a car or something. He gets a little nervous on the carousel also. However, he was in my lap on the ferris wheel and he loved it! I think he does better if he's in my arms which, luckily, is how every situation will be at WDW.
He's very cautious for his age. Other babies his age just flop around in the swing and laugh alot, but he holds on for dear life and only lets a smile slip out once in awhile. But he cries when I take him off.
I guess I'll have to start simple and see how he does. Thanks again.
