For FM do you discard it one month upon opening? Or ok to give some allowance? I store the tin in Ziplock bag upon opening. Currently feeding BM and FM and it always takes more than a month to finish one tin.

Practicality, how many of us are able to keep up with all the parenting 101 golden rule? Personally i do not store the tin in a ziplock bag. I ensure each time after i open the tin, take what i need and keep it close immediately. As long as the milk has not harden i still use it.

My boy can't finish the whole tin wihin a month too. What i did is to transfer an amount into a air-tight container for daily use and keep the rest in it tin. In this case, the milk powder will not be expose to the air and hence, can last a bit longer.

I always keep it into an air tight container. Pour some into a tin which i would use. The rest i keep it in a air tight container

thanks

I stretch to about max 5 weeks
