Just wondering if anyone has used Bio Kult Infantis probiotics. I bought some for my 8 week old and am not really sure how to use it. It says on the box to use a quarter of a sachet for babies under 6 months and to mix it with milk. I can do that, but then is the rest of the sachet going to stay sterile for the next few days while I am using it? If I add it to boiling water to sterilise and then feed the water to my baby, will the boiling water kill all the probiotics? Bit of a random suibject, just hoping someone might be able to help.
