We liked the decorated cow statue at the airport, the doll houses at the Rijksmuseum and the contrasts at the National Heritage Museum, where a thoroughly modern Hollandrama rotated the audience around inside a dome to view historical scenes, while an old-fashioned farmstead had chicks that would eat out of your hand and baby goats that would climb on your back. We fed the pigeons in the square near our Amsterdam hotel with bread left over from lunch at a grand cafe. We got out of the way of bicycles. We learned about odd little things. Toilet seats that spin through a disinfectant cycle.
Trash receptacles that talk.
The sun rose really early and set really late. It looks like it's midafternoon, or maybe supper time, when it's really time to go to bed. The spinning toilet seat was at the fancy Restaurant Plato at The Hague. While the adults had a multicourse lunch there, the children constructed individual pizzas in a separate room, close enough for us to see them, but far enough away that they weren't a bother. The restaurant offers the same option to families who make arrangements in advance.
