What age do our babis Stop getting into everything they can? My 10 month old Suzi got into the bathroom garbagge, and I caught her chewing a plastic aplicater from a tampon

why do they always want to find the most discusting, nasty, filthy thing to get into??? Now I am worried that she wil get ill... Sorry for being so graphic, we were home, and Suzi is usually right with us!
Will this behavior decrease as she gets older? Thanks
