Preparing for an one week trip, would like to ask, one scoop of nan is equivalent to how many grams? Anyone has any idea? And so would like to estimate the amount of milk powder to bring on a trip

Its hard to gauge like this. How old is your LO now? How often does he takes to finish one tin of formula? From there you are able to gauge. But please bring more. I have experience before that my LO wanted to drink MORE then usual while we are out.
