Here's a layout I did this month. Pictures were taken in January and Garrett had just gone to his yearly physical and measured just shy of 5 feet 8 inches. He's grown just about 4 inches this year and now is 3 inches taller than me.
And this was done last year. I was just a smidge taller than him.
Next year, I think I'll measure him up against Chris. He's 5'11 and at the rate Garrett is growing, he'll probably be eye level with him!
