Calls from Santa create a fun exciting experience for your child. And best yet, it's totally FREE! Every year I have Santa call my children on the phone. It not only reinforces that Santa is real, but also reminds them that Santa is watching them. This encourages them to improve their behavior, or atleast it does for my "little problem child".
There are many free phone call services available. Each year, I usually use Google to find one. This is the one that we stumbled upon this year. It's much easier then some because it does not require you to set up an account. Simply go to www.christmasdialer.com and enter your telephone number. Next thing you know Santa Clause himself will be calling your phone!
