Mommy Cards are just a great idea for many reasons. Use them when you go on play dates to share your info with other mommies. Leave them for the baby sitter so they can easily contact your cell phone number. Another idea would be for when you purchase an item and they are going to deliver it, leave a mommy card and they will never have trouble reading your handwriting again! And, don't forget to place them in your child's school backpack, if they can't remember your contact information, it is always close at hand!
