We have been reading the scriptures as a family since Ava was little. We started with the "My First Book of Mormon" board book, then started the Book or Mormon Reader made by the church. Just recently we have started reading "The Book of Mormon for Families". It is the the Book of Mormon, but broken up in smaller sections, with pictures, and has definitions. It has been a great way to introduce Ava to the language of the scriptures and allows us to have good discussions about gospel principles.
Not only do we read the scriptures a family, but Rich and I also have personal scripture time. We have been doing this for most of our marriage. While we are not perfect we do read almost every night.
A couple months ago I decided it was time for Ava to start her personal scripture study. She is starting to read and I thought it would be the perfect time for her to start developing the habit. Of course she can not read the "real" scripture yet, but she can read the board book versions. So a couple months ago Ava started reading the scriptures, with a little help, at night before bed.
It is a wonderful thing to hear her read the words. I have noticed that the stories are starting to take on a whole new meaning to her. She is getting more from them and I think (I hope) developing a love of the scriptures. I just hope her desire to read and learn will continue as she grows older.
