My worry was that it wasn't just letter reversals--which I know is normal--but mirror writing in toto. He often reads and writes words and numbers from right to left instead of left to right. He doesn't seem to get that we Amuricans (smirk) read and write from left to right.
He'll ask "what's 1-4-9," and I'll tell him it's 149, only to find that he meant 941. Or perhaps even 194. Usually 941 though.
That seems more worrisome to me than simply flipping a "b" and making a "p"... (And more like what Soup is describing in her post--you snuck in there on me!
)
He does seem to be a visual-spatial kid though. He's very artistic, very mathy. (But that is yet another reason why his not looking at books when we read them seems troubling.) Maybe he is just an Edison kid.
More food for thought. There's another book I need to reserve at the library.
