One of the beauties of picture books is how they can meet a child right where she is. Learning to ride a bike? There’s a picture book for that. Anticipating a new family member? There’s a picture book for that too. Books let us know, adult and kid readers alike, that someone else has gone through the same thing. So if you’re celebrating one of these dozen milestones with a child, we hope one of these dozen books will come in handy.
