I teach preschool-kindergarten Sunday school, and I also have a child who is 4 years old. I have found it difficult to find Biblically accurate picture books of the Christmas story for this age group. This one fits my children's needs very nicely. They enjoy it and it keeps their attention. At the low price, it also makes it easy to give as gifts.
I bought The Story of Christmas as gifts for my preschool children. I was looking for a child's story version that had the wise men at the house, not the stable. This telling of the Christmas story is true to scripture.
