No scissors aren't a problem, thank goodness. But we do deal with fears of thunderstorms, lightening, heights (no escalators or stairs...thank the Lord for handicapped access), running out of gas, getting lost, being late, dying. He won't go near frogs or most bugs although he is fascinated by snakes. I'm not sure he'd actually touch one though.
Going almost anywhere fun is a challenge. You wouldn't think heights could be such a problem, but going to any kind of play or show at a real theater, the circus, an Omnimax theater, sporting event, water park, amusement park, museums and for a time even upstairs in the mall was a big challenge for him.
He does do elevators but if the space is "open" and you can see upper or lower floors (unlike a regular office type building) forget it!
I hope he grows out of this soon. He's getting heavy!
