DD age 3.6 is very interested in letters - lots of 'what does nursery begin with', 'look there's a n', 'write mummy for me' etc. I respond to her questions but don't particularly introduce any more than that. I try to use phonics but sometimes use letter names as well. I suppose I'm worried that I might be bumbling along doing damage to her emerging literacy through my cluelessness on the subject (fluent reader myself with degree in Eng Lit, mind! Not that I'm functionally illiterate or anything)
