Does any of your leapfrogs know their colors correctly? Im wondering why Alex really doesnt yet-sometimes he will get a few right right off the bat and then just pretty much guess or say the same color over and over. He knows shapes pretty well and abcs and can count to 12 or higher so Im wondering if this is normal at this age or if he may be color blind? We dont really work w him on it to much as they teach him at daycare but will be doing more of that to try to gauge him...what about your leapfrogs??
