I purchased a set of these cards from Bibitty on Etsy, just before Christmas. They really make my son's freshly painted room look complete! I LOVE them! You can also find sets of Spanish and French cards too.
Have you heard that the "cool moms" carry Mommy Calling cards now? I guess it's so you can get in touch with other moms that you may meet at the playground, McDonald's line, what have you. I saw these at PaperRamma and thought they were adorable. They come in a tiny carrying charm that goes on your keychain. What will they think of next?
