Thanks you for doing this! I made one of these a year and a half ago for my new babe and totally winged it. Now a friend has asked me to make her one and I was dreading figuring it all out again! Now I don't have to dread it! Any advice on strap length, etc. for super-tall parents? I made my straps for my short self, and these parents are 6'3" and 6'4"...
