Summer babies are truly something special. There is a distinct, joyful energy that comes with celebrating a little one born during the sunniest months of the year. If your baby is approaching that major twelve-month milestone, you are likely already scrolling through social media, searching for the perfect summer first birthday themes to mark the occasion.
