* not a joking matter* Just got home. First thing, mother comes up to me & tells me she saw the 3yo licking privates of 2yo brother. Mum asks him who taught/told him that. He says "a girl at school" (playgroup). I told her to inform the teachers. She says no, let it lie & see if it happens again. She says she told him to tell her if anyone does it again & told him not to let anyone touch him there. I asked him myself & he again said "girl at skool daddy" I'm not overly concerned but not sure if I'm supposed to be. Interest to know what would you guys/girls would do in this situation?
