like what and when would he comprehend whats what i mean my son does like fish so i know he would love the shedd aquarium but other places.|||the shedd is very easy on little ones it is impossible to get lost because it is built like the spokes of a wheel and with a stroller they can take it easy too.|||I think 4 or 5 is plenty young enough for a trip to the Shedd. Kids 2 and over can enjoy the Children's Museum at navy Pier.|||I took my godson when he was 3 and he loved it especially the dolphin show now he is 4 and recently we went to the zoo..he really loves animals
