J and his cologne fascination

J has decided he needs to wear B's cologne every day. We talked to him about wearing it for special occasions and he has agreed to try that idea. On Sunday he decided that church was a special occasion and he picked out the cologne he wanted. B told him to let me smell and I took a sniff. J said, "Mom, don't smell it all up." Obviously he thinks it can be smelled a limited number of times before it is gone.
We had planned a trip to the store to buy B more cologne the following day and J cried because he wanted to go cologne shopping that day. I am afraid to see how expensive he may be when he gets older. Our family went to Sephora to smell the different colognes and we literally had to drag J out of the store when we were ready to go because he even wanted to smell the all of the women's perfume.
