Powdered Formula - How long to keep?

[MummyNaomi]

I have a large tin of Nan HA Gold 1 and the tin says to used within 3 weeks. As we breastfeed mostly and use formula when out etc (so only really 3-4 feeds per week) there is no way I will get through a tin in 3 weeks, any ideas if it will last longer (I know these used by dates etc are guides only). Perhaps if I put it in a airtight container instead of the formula tin I can keep it and use for longer?

I have tried to find a smaller tin or sachets and cant seem to find them anywhere ...

Any tips re how long to keep it, or if you are aware of where I can buy in sachets or smaller tin please let me know, its so expensive I dont want to throw out half a tin every three weeks

Thanks
Naomi

i think it is usually yes 3-4 weeks.

We have 400gm tins of our formula so it makes it easier for us.
I think with DD when we were using the 900gm tins i would often go over in time but i didnt notice or i weaned onto soy (obviously older - 12 months).

2s6 gold have sachets but they will prob work out the same price.

it is one of those catch 22;s

Yeah i think most tins say 4 weeks.
i have only seen the satchets in the s26

Yeah I think on the tin it says use within a month if opened...have you considered using the little sticks instead? It might save you $ and formula in the long run.

My health nursed advised me when I was comp feeding DD2 that I could extend the life by 2 weeks if I put the tin in the fridge, which I did and all was ok

I saw the 1 Nan Gold sticks at Chemist Warehouse the other day... I bought the s26 sticks though when I was in your position... But when I weaned DS onto formula used Nan HA Gold...
