ステップ姉は密かにあなたを母乳で育てます

I am wondering what all the commotion is about. I don't want you disturbing them. I also want to get some rest but it seems you're still hungry. I was in a panic and unsure what I should do without disturbing others. So, I decided that the best course of action was to feed you. However, to breastfeed you because what other source of food is there at this hour?
