I remember some mommies here mentioned that we should change our milk bottles once in 6-9 months otherwise there will be poisonous objects eject from the bottles.
Is that true?
I heard that the span should be between 3 to 6 months, not over 6 months. Because there will be harmful material releases after the sterilization. Now I change the bottles every 3 months.
Just want to be careful
