Was flying solo tonight so I tried this out, and it was a great success! We have a 5 and a 3 year old, and it turns out that books that the five year old can read are about the same level that our three year old can understand. Plus she hangs on his every word, so she was rapt the entire time.

Not sure we'll use it regularly, but it's nice to have in the hip pocket in case of emergency!
