a)Some parents provide me with bottles of water & powder - I zap in M/W then add powder
b)Some parents provide me with made up bottles to either zap in M/W or in hot water
c)Some give me sterilized bottles and I add water & powder
So based on current advise a & c are fine, but that b is an issue
After gently bringing it up with parents, they have sadi they prefer to bring made-up bottles
How do I deal with this?
It's not best practice, but it is parents decision not to do this
I can't argue or critise them, so what do I do?
