When we go to Gymboree, they bring out the "Busy Box", AKA a big basket full of neat stuff for the babies to pick out and play with. They all focus their efforts, though, trying to pry the maraca out of the hand (or mouth) of their neighbour. Dude, there's a whole basket of maracas for the taking. Oh well, I guess you can't beat the allure of something that is seemingly unavailable.
P.S.: Happy Easter!
