caleb is starting (emphasis on starting) to learn what colors are. actually, i think he gets the concept, just not the wide variety of options. so far everything is either purple or yellow. he's really good at purple (although he does call blue things purple, too) and everything else is yellow. yesterday at the store, caleb was running back and forth along the refrigerated section of juices, pointing to all the cartons that had purple lids. i think he pretty much made the day of several older ladies shopping nearby.
sometimes, caleb even gets the color brown... well, only in one case. if he's holding both his purple frog stuffed animal and his brown doggy, i ask him "what color is your frog" and he says "purple". then i ask, "what color is your doggy" and he says "brown". but if i ask him at other times what color his doggy is, he'll either say "yellow" or "color" :) it's still a work in progress!
