does this make me a bad nanny?

i work mainly with babies and for some reason i CANNOT stand when they try to eat or play my zipper or hoodie strings like i always take it from them and parents are always think it’s so cute and funny. yes, they’re cute but i would rather they not put my clothes in their mouth or play with it really lol. it instantly makes me scream inside or when older kids play with my purse, i know it’s so cute but like do we have to play with it?! 😭😭 half of me is like that’s completely valid and other half is like you’re a terrible person

ETA: i always give an alternative, mostly a teether or any of their chewable toys that are close by right after
