Just gross

Why is it that some kids just KNOW when things are gross? Almost everything is gross to Hannah, always has been. She never liked even finger painting because her hands would get dirty. Not my girls. It seems they have no concept of gross or germs. A few nights ago Nyah finished her milk and went in the bathroom to brush her teeth before bed. I followed mere seconds later to find Nyah pulling her toothbrush out of the toilet water and was about to stick it in her mouth! EWWWWWWW! Ew ew ew ew ew ew gross! Aparantly I had not moved fast enough and she thought she’d start brushing her own teeth but needed to get it wet first. Needless to say I took the toothbrush away before it touched teeth, but Nyah couldn’t understand why. As I was explaining Jasmine came in and asked what happened. I told her Nyah had stuck her toothbrush in the toilet so I had to throw it away, and Jasmine asked why too! Am I doing something wrong here? At 9 years old she doesn’t know that toilets are disgusting germ filled cess pools? Ugh! So I explained all over again, lets just hope I don’t find them eating yellow snow at some point!
