Loved it!
I took my kids while the walkout, they are toddlers, and they were crazy about everything! I do agree it's a small museum and at so point with so many people it gets crowded and you REALLY need to watch your kids...I think that's the feeling when they offer Free admission days...I wish they had a capacity limit per room-area.
They explored the train, that has a video inside and you can watch and pretend you are driving, so simple...but my kids kept going back to play here like 4 times....also they have a "pretend to play "areas where the kids can be in a restaurant, play with the food and inside of the kitchen, also there's a library a theater with puppets some clothes to dress up and some musical ins to perform, so nice!
Also you can pretend to be veterinarian, dress as them, heal puppies and check their x-rays.
