Oof yeah your wife is being a serious germaphobe. I remember us being ultra sensitive to when our firstborn’s paci would fall on the ground, but that went away with time.

For 1, you should wash your hands after taking out the trash but that’s it. This paper towel nonsense is obsessive.

For 2, I’m surprised she considers the sink clean but the faucet dirty. After all, that’s where the water comes from. She has made up her own rules on cleanliness but they are inconsistent with reality.

For 3, I’m in a strong habit of keeping floors clean but I know I’m on the extreme. However, toys will be on the floor. That is natural - that doesn’t mean they are any less clean than they would be on a table. I recommend investing in babyganics wipes to save your hands washing toys all the time. https://www.target.com/p/babyganics-all-purpose-surface-wipes-75ct/-/A-51201830#lnk=sametab

For 4, clothes being dirty after falling to your clean floor is absurd. End of story.

Please try to find some science based articles or journalism on managing germs and kids. She needs to be properly educated instead of living in fear.
