Mirror book: I admit to bringing too many books for Rory in the van but if you are aiming for minimal books than make sure it’s a mirror book. It’s a magical developmental milestone when baby looks at his/herself for the first time. The laughter, love, and hours of entertainment with a simple mirror book will be well worth the minimal space in your car. Depending on your child’s developmental level he/she may be able to hold the book on their own for individual play on long car rides. Rory was able to do this with books towards the end of our summer travels as he neared 10 months. Even if baby cannot hold the book up on their own, being able to grow their self identity and confidence is a key concept in the early years.
