Every time I mail off a note or some breastfeeding information I attach a calling card with my phone number and email address in hopes that they will hang on to the card. I use address labels with the date of our next class on them if the client will still be pregnant at that point. If not, I use cute stickers from noodle soup.

let me know if you have any tips to add!
