Take water volume or total volume with formula to calculate volume consumed
For 180ml of water with 6 scoops of formula powder, do you take the water volume (180) or the total prepared volume (200) to calculate how much your baby drank?

depends, if I'm at home, I'll put 180ml of water then put the powder. if I'm bringing to ifc/childcare, I'll put powder in dry bottle and label with "put water till 200ml" mark.
Take the water volume not the total prepared. Water first until 180ml before adding 6 scoops of formula. That's the correct way.
For me, i measure the water volume before putting milk powder.
take water volume only; before putting formula in
