I love how the kids take a photo of the grandkid, next to an age sign, each month. This way we get to follow along with how much the grandkid changes little by little, month by month. It can't help but make you feel like you are part of the process, action, and fun.
This is especially fun if you, as a grandparent, are not able to see the grandkid very often, or you need more photos for show and tell at girls night out. Either way, it is kick-and-a-half.
