Comparing UV sterilised VS new baby milk bottle (plastic made) - NO! Don't UV sterilise your plastic bottle!

After few month of constant UV sterilised my baby's bottle. Let's check out what changes it does to our bottle.

I have a UV sterilliser at home to help me dry and store my baby's bottles - Haenim Classic UV Sterillizer

I wasn't sure until I read the bottles manual, UV sterilising isn't a recommended way by MAM as it'll degrade the plastic bottle. Doesn't matter which brand you use, as long as you sterillise a plastic bottle, it'll degrade as you UV sterillise it. The more you do it the faster it degrades further.

This is a very short article to compare between a 2 new and old milk bottles (bigger = new, smaller = old).

See what has the UV sterilising has done to my bottle. UV degrade the plastic bottle, and it become yellowish and lost some of its overall elasticity on certain accessories. 

Both were bought in same white colour.

They both were bought in same white colour, but the smaller bottle at the right became very yellowish after underwent months of daily UV sterilise.

I'm not sure if this level of degradation is still safe for baby feeding, but for the safe side, we better get a replacement or a non-plastic made bottle.

Dissambled items of both bottles

Every parts of the bottle became so yellowish. The valve (2nd item from the left), even though colour don't differ much, but it has become less elastic and rougher to touch with compared to the new one.
