I've tried to show Iona the "Mummy", "Daddy" and "head" flashcards at least once a day since my last post. She now says "Mama" as soon as she sees them. Unfortunately, that's true whichever one I show her! However, when I show her "Daddy" and correct her that it's not "Mummy", then prompt her with "Da..." she excitedly says "Dada", so I feel that's some progress, especially at only 13 months old.
