Thanks for taking the time to provide feedback regarding the books you received. We’re very sorry you felt the titles we delivered were too advanced for your grandson. While we strive to identify interesting and unique reads that are age-appropriate, we realize each child is different. That’s why we also have a great board book subscription for slightly younger children and of course our 30-day guarantee. It’s important to us that when we miss the mark that we strive to make it right. We’ll reach out to you privately to see how we can best address your needs.
