Probably the best book subscription service out there for kids!! I have always done alternating book boards and picture books and my daughter loves all the books. At 12 months she knew the ending to sentences and learned so many new words. At 2 years old, her vocabulary and word articulation surprises me each day. She speaks in sentences and now she knows what sentence is coming in a book. All the books that come in have a great story or learning tool to use. I'm so lost when I go to the bookstore because there are so many books to filter though, Bookroo does a great job at curating the books and to send out. Bonus: I love the wrapping paper they come in. It's like a present each month my daughter looks forward to opening.
