How often do we need to change milk bottles (not teats)? My milk bottles have turned cloudy from the sterilisation, wondering if it is necessary to get new bottles.

Change it every 6 months for the bottles, and teat every 3 months

Sounds normal. To change bottles around 6 month, tears 3 months.

Yes. Should change every 2 to 3 months

Bottles 6 mths. Teats about 2-3 mths

Same. Change every 5-6 months.
