We've been reading these books for months and one day Tanner started imitating things we do as we read to him. Now, sometimes it only takes seeing something once and it sticks. This is one of his favorite books. But I think he likes Happy Feet the best. There is a scary picture where a big fish is chasing Mumble and I taught Tanner to scream. Now when we read it he goes right to that page so we can scream.
