Remember when you had to hunt down your immunizations at your old pediatrician for your college or grad school applications? Well, you could make things a lot easier for your child if you keep good health records for them starting now. How nice would it be to be able to hand them this little book when the time comes.
We have a little booklet from our pediatrician for a record of immunizations/growth, etc, but we sometimes forget to bring it. Having something like this might get us more motivated to keep more careful records all in one place.
Would also make an unconventional, but thoughtful shower gift.
