I am a childminder
I breast fed my DD & didn't do bottles
I had a baby today who is poorly & we are recording how much the baby drank so ensure he isn't dehydrated
So 7oz water plus 7 scoops of powder = how much milk (cos it sure wasn't 7oz by the measurement)
So if there were 4oz left in the bottle how much was drunk
It doesn't really matter because I recorded how much was left in the bottle - but I was just interested
