We gave this to our 5-year-old son as he started school, saying that since he will be gone from home more often, we wanted to let him know that if he ever felt he wasn't getting enough mommy-daddy time, to give us a coupon. He loves it! There are a lot of coupons that are a little more appropriate for an older kid, even through a teenager, though I don't think I'd give it to a child younger than about 5. I told him we won't always be able to immediately do what the coupon says (like the coupons for an outing), but that we will plan a time if he redeems the coupon.
I bought one of these for each of our boys for Christmas. They are so excited about all of the fun things included for my husband and I to do with them. We already enjoy spending time enjoying our children, but this coupon book has things in it that we may not have otherwise thought of.
