We were lent a set about 5 years ago, (girls were 6, 4, 2, baby) and over the course of about a year and a half, I read the whole set aloud to them. My girls really enjoyed it at that age.
I even actually ended up using one of the stories from it to teach a Sunday School lesson one time because I liked how it dealt with the story (Bathsheba and David).
So, I’d keep them……but if you need room, the Golden Children’s Bible takes up a lot less space and is well-recommended, also……so, I’d get rid of them…….*L*
