When our kids were young I tried not to said the f and s words in front of them 😅 but now they are older and went to school 😢 sometimes I said the four letter words they would tell me not to said them I would apologize to them 😅 I understand as a parent we would like our kids grow up to be a good and kind hearted person and I can understand your worry about UU picking up the wrong habits 😮
