Avent milk bottles

I replaced them every four to six months. If you see any cracks, leaks or chips on the bottle, discard it immediately.Discoloration of the bottle is another warning sign.

Milk bottles are made from plastic...thus the frequent change. Depending on how frequent the bottles are used. Glass bottles are the best. Downside, heavy and fragile.

Hi... it is recommended to change feeding bottles every 8 to 12 months.

I used it for half a year and sterilised after use every time.
