My husband and I recently visited the MN Children's Museum when my son had a field trip there.. and it looked like great fun.. IF I was a kid.. But that is how it is suppose to be. My son loved the area for babies and toddlers, even though he is almost out of toddlerhood. And he loved the water in the one big exhibit hall.
Of course the downfall is, the place is almost always busy.. so my son did not get to play with everything he wanted to.
