Spectra Milk Bottles

Hmm, are you using uv sterilizers? PP plastic will age very fast with multiple rounds of sterilization and will need replacement. If unchanged, hormonal disruptors may start to leech off the plastic. Best to use ppsu bottles, they can withstand more rounds of sterilization and require less replacement https://shopee.sg/product/242594539/5732034154?smtt=0.0.9

Same. I steam sterilise it. I do continue using for about 4 months.

Yes. I continue to use them until baby turned to 7 months.

Did you UV the bottles? If yes, it’s normal.

Mimr still looks OK after 2 months plus

Yes
