I love this place! They switch up their centers every so often so that the kids don't get bored. I've brought a wide range of kids from as young as 5 months up to 6 years old. They always love it! It was very difficult the first few times to find it (we drove round and round ...) but that's not really their fault.
I'm editing this to add: The last few times I've went, I've needed to warm up a bottle for the baby. Unfortunately, they don't have any way to warm up a bottle in their lunch area, though the ladies at the front desk are always willing to help. I usually just bring a large drinking cup, and they fill it with water and heat up the water in the microwave. This lets me set the bottle in the bowl to warm up the milk instead of having to put the bottle in the microwave where the ladies could overheat it.
They also recently changed their rules. Artville requires socks for kids AND adults. You can buy some from them, but just be prepared to bring socks or pay for socks to go into that half of the museum.
