Our visit to the Museum was actually in April 2008, so I daresay I'm a bit late in making my review, but I assure you - my opinions are the same! We took our 2 year old to Indy expressly to visit the Children's Museum, as they were having an exhibit featuring Curious George (a favorite in our house). I was a bit apprehensive before we arrived that the only thing that would draw her attention would be 'monkey George' and the Toddler Area. Boy, was I wrong. While I'm sure she missed the point of the river - directional room size waterway, she had a ball sailing her boat around the entire circut and following it along the way. Older children were kind to her and showed her how to do the pool ball kinetic machine, and she showed her ingenuity in the factory/blocks discovery area.
Four floors of fun - I assure you. I would say children up to about age 10 would really enjoy the experience the most - and clearly as young as 2.
The toddler area was inviting, and as it wasn't our first stop in the Museum (we went all the way to the top and worked our way down) It included a soft play area for those even younger than ours, several playmat type areas and a real (small) Caterpillar bulldozer to sit in. All in all, by this time (nearliy three years old) our daughter would be bored there with all the other options.
4th Floor - included the pool ball kinetic machine, really fascinating to play and watch, even my hubby was engrossed. Also the waterway learning area. This level also included a science area which was more for older kids - indigenous species, watershed areas, etc. There seemed to be a presentation on fossils or some such thing going on as well that older children were participating in. Also a 'worm tunnel' climber and slide that daddy had to investigate with darling daugher as well.
There is a working carousel, which costs an extra dollar, I think, and was well worth it - authentic old fashioned horses etc. A fun house mirror maze, many large-size games (Connect 4, Plinko type).
There was a dollhouse section that did not keep our toddler's interest, naturally, but older girls and moms alike will love the miniatures (especially if you are like me and had a real dollhouse with scale furniture when you were little).
The Curious George exhibit was incredibly crowded (naturally) but was well-done. I think our daughter did the rocket slide 87 million times. She would never have left, given the choice, despite the congestion of other families/children.
The slide from the 2nd floor to ground level was fun. We probablyi would have done that twice if we weren't actually trying to leave. The cafe downstairs offered box lunch type items, along with hot meals - chicken strips, burgers, grilled cheese I believe, etc along with grown up salads and sandwiches. As par for museum food - a bit pricey, but not so that we felt robbed to eat there.
I'm sure I've missed other details, but all in all a fantastic day - made for one pooped 2 year old, but I've raved about the museum to anyone who will listen since then. A grand day for our family.
