Well the day we went it was super busy, then again it was the weekend. There were a lot of kids at it I think the youngest was about 2ish. It was cool though when I was looking at the reproductive organs there were two kids (5ish maybe) who's parent's were using it to explain a simplified version of the birds and the bees. I think it makes much easier for the parent's being able to point and read the explanations of the organs as the kids were asking questions.
