Last night I measured DD (4) with her normal shoes on, and these shoes do not have much of a sole. I took out of ruler.. laid it level on her head, marked up the door and measured. She measured 40.5". with her other sneakers that have a little more cushion, they measured 41". And with some boots she has, she measured at 42". The rest of our group is at least 45 inches.. and I know she would feel left out if she could not do Grizzly Run. Can someone tell me how they measure small children for the height restriction rides?
