My oldest has ADHD and struggles with lots of impulsive behavior, including outbursts of rage, extreme frustration, and stealing, within the past year it has spread to stealing from a store. This book, and the whole series actually (we have several,) is written perfectly with our style of parenting (like returning stolen items and apogizing to the manager, emphasizing the importance of God, prayer, and asking forgiveness.)
My son keeps them in his underwear drawer so he doesn't lose them and that his sisters won't mess them up.
I purchased almost all of these little books as a social and spiritual tool to use with my 3 kids. I was especially excited to have them read them as part of their "punishment", while cooling down perhaps, when they displayed such behaviors. I think they will be great in reinforcing what we already teach the kids, except it's not just mom saying so, they are accountable to God. Each book reminds them also of forgiveness through Christ's sacrifice. I didn't have to wait for troublesome behaviors to read these. The kids were immediately drawn to the books and had me read them right away, one after the other without any misbehavior. The books are quite small, but I think that's what makes them so appropriate for the suggested ages. Short and sweet, I recommend these books.
