T.B.
My son went on the American Eagle when he was 4 but they have since raised the height limit. My other 2 girls started to go on the wizard when they were 4/5 and this year my 6 year old went on the Demon also. She would go on them all if she was big enough. The ones with the highest height limit like The Bateman, Superman, Ironwolf are because of the type of seat. They all have a seat by the entrance you can try to make sure he fits.
