The Toddler's Bible http://www.amazon.com/Toddlers-Bible-V- ... 0896930777
is very good and so is The Preschooler's Bible http://www.amazon.com/Preschoolers-Bibl ... 156476317X
They are pretty similar - I suggest you just get one or the other, not both of them.
Those are both great for little ones.
Then the My Little Bible series is good for preschoolers http://www.amazon.com/My-Little-Bible-S ... 0849908248
and there are other good bible story books available too.
I think it is great to read to children and to read the Bible to them from a young age as well.
