If you are interested in a website that will allow your child to hear some wonderful books when you are not able to read to them, check out One More Story. There is a subscription fee, but you have hundreds of wonderful books at your fingertips. There are also options which allow your child to read along or echo read the story. Any story that your child would hear on One More Story would count on their Book It! story log form.
