When our grndsn was 3, he went on everything he could with a little flashlight for the dark, when he was 5 he would not go on anything that was dark or loud, now that hes 6, he has a list of rides,still nothing thats dark or loud. I think 3 and 4 is a great age because they are not yet afraid of too much. Going back in April with the 6yr old, cant wait, way to cold here at home. Oh yea at the age yours is at dont forget to go on buzz lightyear.
