Hmm I was thinking about like a colouring book, or those books where kids can learn how to write and how to do these little math things.. but then again, is he going to school? Cuz if not then maybe he doesnt even understand it.
Or you could send him some coloured paper, like they sell in these little packages with all these colours? (well they do here) and then you can make all these different things of it. I loved that when i was younger..
or maybe you could send him a beachball (cuz that can go in an envelop) or like a little car or maybe those little soldier things guys play with?? I dont have any brothers so
