DS will be 3 in July. He can count quite well from memory, but if I ask him to count items in a picture (eg. how many fish are there?), he gets muddled and a lot of the time doesn't count them properly. He also knows basic colours, but when I say (for example) "what colour is that ball"?, he will sometimes count them instead. Should he be a little more advanced than this at his age? He seems quite bright and figures things out quickly, but he also has a short attention span and has NO interest whatsoever in drawing, painting or colouring. Just wondering if this is normal.. thanks.
