N.P.
we've been taking our girls since they were infants and they have loved it at every age. They get different things out of it each time, according to what their age is. We had a membership to Museum of Science and Industry from when Tara was about 9 mos till 27 mos old and she LOVED it, we did too. I really think it helped her learn a lot of new things and be more outgoing. By the time she was 2 she had been to every museum in Chicago at least once.
