Hopefully someone can help with this.
I have been using the ready made cartons of SMA but as we are going through them like nobody's business I have just bought a tub of the powdered SMA.
It says on the tub to prepare each bottle as you need it, but as you have to boil water and then leave for half an hour before making the bottle, this seems less than ideal. Cannot imagine doing that in the middle of the night!
Can I make up a batch of bottles during the day and then stick them in the fridge to be re-heated as necessary throughout the evening and night?
