I picked out three - one for each boy, and figured we would give them a shot. Pierce got The Lion, the Witch, and the Wardrobe.
These are so awesome. The boys can slip them in a pocket and listen as they play Legos or work puzzles. They are easy to use, and I love that they let each boy enter the world of reading at their own convenience.
I enjoyed having some moments of silence in my house, reduced squabbling, and some random bursts of laughter (Cort and Reid both had more humorous children's books).
Readers, have you heard of Playaways?
