The playground can be quite the social scene. When my son hasn't had enough of playing pirates or swinging alongside a new-found pal, I'll suggest to the other momma that we schedule a playdate for the future. But checking calendars and adding new contacts with children in tow can be quite a challenge (if not chaotic!), which is why I simply adore these calling cards from kate spade. Easy to carry and ultra-stylish, these cards make exchanging information a cinch!
