You’ve shown no interest in riding your rocking horse until this evening. Papa was over tonight, and he was playing with you in your room. You walked over to it and crawled on, and with his minimal support, you started rocking it. You ‘talked’ excitedly and hugged your legs around the horse to keep you. You loved it. You then got off, carried the horse into the living room and rode it some more. I’m not sure what fueled your desire to ride him all of a sudden, but you sure enjoyed it.
