We are teaching Matthew the alphabet at the moment, and he is comming along nicely. Even though he is 3, he can count to 13 on his own (which is apparently very good) and is getting there with the alphabet. Although he isn't able to recite it much, he can spot the letters and tell us what they are.
Apart from two letters that is. These letters are W and U.
When I say U he repeats back "me!" and when I say W, which I pronounce as "double-u" that is exactly what he hears and repeats back "double me!".
How on earth do you get through to a 3 year old that it isn't double you, but two letter U's put together? I'm sure he will work it out eventually!
