One of the tactics that we learnt to get Rayyan's attention is to act silly! For example, the other day, Hubby juggled the balls in a silly manner and Rayyan totally loved it, jumping and laughing away! Hubby then tried to get him to do some tasks before acceding to Rayyan's request to juggle the balls and Rayyan did all that he was asked to do!
Then few hours later, while we were sitting at the sofa, Rayyan went to his room, took all three balls used by Daddy earlier and passed the balls to Daddy because he wanted his Daddy to play silly again =)
