YOU SAID:
do not sit on the baby, that is not the job of the babysitter
INTO JAPANESE
赤ちゃんの上に座らない、それはベビーシッターの仕事ではない
BACK INTO ENGLISH
Don't sit on your baby, that's not the babysitter's job
INTO JAPANESE
赤ちゃんの上に座らないでください、それはベビーシッターの仕事ではありません
BACK INTO ENGLISH
Don't sit on your baby, that's not the babysitter's job
That didn't even make that much sense in English.
