This is a cute board book, but the main feature (scratch & sniff) leaves a bit to be desired. If it had been possible, I would have given it 3.5 stars.
There are six pages with the following scents: gingerbread, gumdrop, chocolate, lemon, peppermint, and marshmallow. The smell circles are about the size of a quarter, which seems a little small, and they're only faintly outlined, making it hard for babies/toddlers to find the scent. And while the gumdrop and lemon are great, the chocolate and marshmallow don't have a very realistic smell, and I can hardly smell the peppermint.
I also would have liked there to be a least two scents per scene. For example, on the "Dad is fishing on Blueberry Juice Lake, while Mom is baking a chocolate angel food cake", the only scent is chocolate. This would have been a perfect opportunity to do both blueberry on the left page and chocolate on the right page.
Overall, this is a cute story, but it would be better with better scents - larger, stronger, and more frequent.
