At 15 months old, my son is just starting to love books and all the experiences that go with them (browsing, choosing, sitting still, looking at the pictures, turning the pages, etc.). He has begun showing a clear preference for books with photos - especially photos of other babies! Here are our favorites, some of which we've bought and some we keep renewing from the library.
I like to think of this genre as non-fiction for the youngest members of society. Books like these show real people and experiences (which, according to a few sources, is what young children prefer anyway!), offer a fantastic opportunity to teach meaningful vocabulary, and foster a sense of human connection across all kinds of cultures. If you have a baby or toddler who is just starting to look at books, consider offering some with real photos.
