I don't know why this sparked the little spot of inspiration but this could be really cute to do for a little one. a height marker along with a "when I grow up" chart and mark that each time you measure them :) That could make a cute little memory
Livy just asked me this morning to mark the wall with her height, this is such a good idea for kids. Cute DIY: Turn a into a large ruler for the wall, and record the height of your kids as they grow. You never have to worry about moving to a new house!
