Does anyone know of any really good sensory books? A long time ago I bought "Have You Ever Tickled a Tiger" by Betsy Snyder. My LO one loves it. We have been trying to find others for her, but we are coming up empty. The book has a few touch and feel materials. Her favorite is Velcro and it is sooooooooo cute to watch her rub her fingers on the hedgehog's side.
