Hi I have just started using colief as we have noticed a pattern in LO's crying and thought it could be colic. On the packet it says the bottle must be used within half an hour of colief being put in but what happens if you don't? I put boiled water in bottles and take the powder up and add it in the night when she wakes. But the bottle has to be warm, so will I have to make bottle in the night, warm it, add the colief then wait half an hour (which the packet suggest) then feed her? Not very practical with a screaming baby! Anyone got any ideas?
