He's funny because it's almost as if he just isn't interested. He has known how to spell his name since 2 and the letters in his name. Then he'll almost play games with you if you ask him what a letter is. Like, i'll show him C and he'll say 'G' laugh and THEN say C. He definitely knows some better than others, but he just seems more interested in words. His sister will point to a word and sound it out to him (she loves being the teacher) so he loves that and wants to just do the words. I'll try those other games you suggested, but he may just do it on HIS own time I guess. lol. Maybe I'll have his sister play letter games with him!
