I am another one who is always flabbergasted at complaints that there is nothing for children in WS. Granted, there are no rides at the moment. But there are certainly enough attractions and live performances to keep them entertained. Here's a few off the top of my head:
Phineus & Ferb adventure
Character M&Gs at almost every pavilion
Gran Fiesta boat Ride
Mariachi Cobre band
China pavilion movie
Chinese acrobats
Miniature trains in Germany
Flag waving performance in Italy
The American Adventure
Voices of Liberty
Taiko Drummers in Japan
Traditional singing group (I'm not even going to attempt to spell it) in Morocco
Impressions de France movie in France
Serveur Amusant juggler in France
British Revolution band
Children's maze in UK pavilion
O Canada circle vision movie
Lumberjack show.
Now, granted, not every attraction (like the last one listed

) will appeal to everyone. But there is certainly enough to keep them from being bored for at least one day.
