We brought our 5 year old son here this past weekend and he absolutely LOVED it! We had to practically drag him out of there after 4 hours! There are so many wonderful attractions for children. He loved the play grocery store and the bubble room as well as the construction zone. There was a caterpillar exhibit that was awesome and I also liked the Japanese house. We thought the pricing was reasonable. We walked to The Barking Crab for lunch which was great and the museum is literally right around the corner from the T (silver line). We live 3 hours away which is a bummer because my son is already talking about going back!
