This is confusing me a little, maybe i'm just being dizzy but here goes: Q1a. If you fill the bottle with 7oz of WATER then add the 7 scoops of MILK, but it now LOOKS like 8oz in the bottle, do you say thats an 8oz bottle or 7oz bottle?? Q1b. So if your LO leaves 3oz of milk, is that a REAL 3oz 'cos you counted the bottle as 8oz or is it really 3.42oz 'cos that'll be 8oz divided by 7oz = 1.14 per oz (then x3) ??? Does this make sense?? lol I know its silly that i'm being so fussy over minor detail but it's doing my head in lol!
