Books are an incredible tool for speech practice. They inherently add a literacy component, create context and help make sessions novel and motivating week to week. Here are my TOP TEN favorite books for working on the lips-to-teeth movement (aka labiodental control) for F (/f/).
When introducing a new movement, my mantra is fewer targets and more repetitions. This means initially I am looking for books with opportunities for a LOT of repetition of a few target words. I am also very mindful of the vowel context - particularly with children who have childhood apraxia of speech. I consider what I call a "speech compass" as I'm selecting targets.
