Sorry to be a bit thick but I'm confused. General advice is to sterlise bottles until lo is 1 year old, but my ds is 9 months old and taking ready made formula from tommy tippee cups so do I need to sterlise these if the milk is already sterile (as opposed to powder)? Advice on the carton says it's ok not to from 6 months. And is it the same or different for bottles if using ready made?
I'd assumed extra caution with bottles because they are more fiddly and old milk could get trapped.
Cheers.
