My DS2 is 2 and a half and surprised me the other day by naming most of the letters on the front cover of a book we were looking at, off his own bat. DS1 who is 4 never did it that early. I'm sure it's probably not that unusual, and can probably be explained by him playing with an electronic Thomas the Tank Engine alphabet toy thingy, plus watching Super Why. (we've certainly never taught him anything like that)
But if he's showing a natural interest in letter names etc, is there anything I can do/particular types of books that we can look at to encourage his interest? (apart from carrying on reading to him as we've always done?) And are we better referring to the letter names rather than the sounds, if that's what he seems to be picking up? When DS2 learnt to recognise his letters at preschool he started with the letter sounds rather than the letter names.
I'm kind of expecting a fair number of replies along the lines of "just carry on reading to him as normal and forget about formal learning of letters until he's older". But just thought I'd ask.
