Cute book for babies!
Format: Board book
Bought this for my best friend’s daughter for her 1st birthday along with some other little beach items. Me and her both have many fond memories of our beach trips throughout the years together. We both have daughters 2 months apart and can not WAIT for all our future girls beach trips together! 🏖️ She absolutely loved this adorable little book for her little one!
