I told you that Ben learns very quickly when things are put to music. I would guess he is a bit of an auditory learner, like his oldest brother.
Ben learned the months of the year in correct order in less than a week just hearing it put to music. These aren't easy words to say for a child learning to talk English so it took me by surprise when he started rattling them off to me at the grocery store out of the blue! I realize he has no idea what these words actually mean but it's a start.
