Same here. I always "knew" that get dirty naturally through what nature provide us human as a way to boost our immune system and I encourage that to my children too. My co parent not agree with me. I told him, if they are going to somewhere "less hygiene" someday, they are the one who will get sick first because they don't have enough natural immunity in them. Then he called me how barbaric, thats why they have vaccines/synthetic immunity. I feel upset he didn't get it.
