Not really living close to my side of family, I've been trying to figure out a way for Mia to remember who certain people are, and I think I finally found one. What you need to do is make a picture book of any family or friends that call your house or cell regularly. You can buy little photo albums for a dollar at the dollar store, and then just slide in the pictures. This when, when someone calls, you can show the picture to your little one, and they will be able to match a face with a voice. Of course Skype helps this along too, but we're not always by the computer, or able to sit down for a long conversation. You can also use the pictures to practice for a family reunion (so your kids won't be afraid of the people that are excited to see them, and might hug them), preschool, playgroup, etc.And since children like things to be predictable, this idea is a great way to prepare a shy child for what is coming in the future that will be new to them.
Have you done something like this? Did it help? What event/task/etc did you use it for?
