Accidentally give more formula

I accidentally gave my newborn more formula. I had tried a few different brands on my first child. All 1 scoop 30ml. So my second born i tried grow , my mistake i didn't read it was 1 scoop 60ml and i gave her 2 scoop w 60ml water since ytd. I just realized only today. What shld i do? She is sleeping well, not fussing only drinking lesser. Guess cos too much milk. #advicepls
