How do you feel about growth charts? Do you have one at your house? Or do you just mark the wall somewhere? I've been on the look out for a good growth chart for years. Years! I wanted something simple and move-able. I think I found it. It looks like a big giant ruler. Isn't it fantastic? I'm so pleased.
