Real grown-ups might already have one of these in their house, but I am just getting started. I'm doing this to help Julian learn his grandparents' faces.
I recommending assigning this task to family members, both to create less work for you and so that no one complains that they don't like the picture you chose. Call all the grandparents and tell them to bring you a framed picture for this wall. (They should be highly motivated when you tell them it’s for baby to get to know them better. ) To build an outing around this, go out to a frame store and decide what kind you want. Or check out (pictured here) the Picture Wall Company product that will make this as easy as possible.
Once your wall of fame is in place, walk by with baby and point everyone out and say their names. Progress note: Julian is sort of saying "grandpa" as of yesterday.
If you want to get high-tech and achieve the same objective, check out BabyMeetsFamily.com. It's a video, sorta like Baby Einstein, that includes pictures of your family and you. You upload the pictures on the web site and then they mail you a custom DVD.
