My DS LOVED the science museum as a preschooler. And still does of course! Even more than the children's museum. We spent a lot of time in the dinosaur room! My DD3 loves the dinosaur room too. They also have great kid's programs and summer camps, even for preschoolers. My daughter is going to her first one this summer!

I used to get the eye roll for my DS ALL the time when he was 2 to 3. He was always trying to disassemble stuff. And he was usually running or climbing! He rarely showed his stuff out in public. My daughter loves to show off for the public though. People comment on her all the time and her vocab.
