The beginnings of reading?

I'm hopeful that my attempts to teach Iona to read are beginning to pay off. Although she usually still tends to say "Mamma" when she sees all 3 cards, she is usually quicker to realise what "daddy" says. When I lay 2 cards out and ask her to find a particular card she is now usually able to do so, and on 1 occasion last week as soon as she saw the "head" flashcard she put her hands to her head!
