matching shoes/boots

Garrett has been having problems with getting the correct shoe/boot on the correct foot. I am always having to have him change his boots around. So yesterday i remembered a little trick that I had done with Robert. I took a permanent marker and put a little dot on the inside of both his boots. Now to get the boots on the correct feet, he has to first make the dots kiss (or put them together) then put on his boots and they will be on the correct feet. Just something simple, but it saves a lot of frustration and a little bit of time.
