I found this via Seesaw Designs blog.
Here is my awesome chart that my mother-in-law made for both boys:
The giraffe, C and W are cut from Chris and Dave's old chart and Diana stitched a tape measure on the front. The second photo is Chris and Dave's original measurements sewn on to the back, which I love to look at! It is so neat to see how compared to each other knowing how tall they are now, and how they compare to our boys. Thank you so much Diana!
