DS was on 2 bottles a day which worked perfectly as it was one sachet. Now I've dropped the morning bottle so was wondering how to make it up as I only need 8oz a day - do any of you split the powder in half (and if so how?) - will it last for longer than 24hours once opened? I would feel guilty throwing the half I don't use away.. seeing as it costs the NHS £4 a sachet!
Thanks.
