Need advice Family babysitting.

I need advice on how to ask my sister in-law if she would watch my one year old for the night. She has four older kids of her own that I watch after school five days a week. I was just wanting a polite way to ask her.

Do you have a difficult relationship? I would just ask her. Does she pay you for watching her children? If she does I would think you would need to pay her for watch your child.
