A friend complained about the smell of his kid’s poop and the lack of warning. It made me realize I have never really been bothered by poopy diapers from Fleur. But, I may have just gotten lucky.

I think there several factors at play.
- Epigenetics make parents sensitive to certain smells. Nausea defends against poison.
- The epigenetics play into his digestion by affecting the processes involved. This can make certain smells with various foods.
- As a child’s microbiome develops, the altering of the bacteria composition can affect smells.
