new avent bottles - are they meant to be cloudy?

[Jacksmybaby]

Just bought new avent bottles in anticipation of DC2's arrival - have not used bottles for a few years - are they meant to be cloudy? Old avent ones were not like this. Is it the new BPA-free material that makes them like this?

yes, it will be the BPA free material that is making them cloudy.

Thanks.
