Hi, Can you help me with the words above?? I would like to know the most appropriate option for different contexts. For example: - Kids / babies: "I'm going to clean your bum and change your nappy/diaper" - Doctor: "I must give you a shot on your buttocks" - Friends: "Jenny, stop smacking my butt!!" Are all the contexts given above correct or would you use a different option?? Maybe you can illustrate it with some more examples... Thanks in advance!!
