pinkyj: haha im too good at summaries, not good at details.
Ok, i think whats most important is that the water should go in first. Dont add less water than whats neeeded.
So if its 120ml you are making, ensure only 120 (125at most) is in thebottle.
Then add the required powder.
Of course with powder added, water level increases, but its not like water is increasing so its ok for level to go up.
Then mix and feed lor.
You are still feeding bb 120ml of milk, not 130 or 140 or whatever it goes up to.
