I came across some great books at the used bookstore here in town. They are “The Story of…” books. There’s lots of stories, from George Washington to Easter. And the faith-based books are some of the most accessible I’ve seen for children. The author is Patricia Pingry. I bought several for T-Rex including the stories of the ten commandments, Easter and Jesus.
One thing I really 
like about these books is that they aren’t wordy. There are few enough words to keep your young toddler interested. There are also other things to keep their attention. T likes to point out the “puppy” and the “boy.” She also likes the picture where the family is praying and we usually pause to say a prayer on that page. The concepts are also easy to comprehend, like describing the commandments as “God’s rules” just like we have rules at home and at school.
We’ve been looking for some good introductory books and were so grateful to have run across this series.
My parents have one of these. Good stuff!!
