at the airport, without getting on the nerves of all the other passengers? You want to have the little darlings racing around and tiring themselves nicely before the flight, but can't be antisocial! Any tips? All I can think of is 'Simon Says' with things like jumping on the spot and twirling round and bending down/stretching up.
I think all airports everywhere should have a (free) softplay, by law. Also departure lounges need to have giant hamster wheels to burn off any leftover energy!
