The shelf life of three kinds of bottles with different materials is also very different. The shelf life of plastic milk bottle is 3-5 years, and that of stainless steel milk bottle is 8-10 years. However, glass milk bottle has no shelf life and can be used for a long time. However, the long-term use of milk bottles, the reuse of health and cleanliness is far less than before, in addition to the previous said that the milk bottles should be thoroughly disinfected, re purchase of new milk bottles will be more healthy and sanitary. In addition, the nipple on the bottle is easy to age and needs to be replaced at least every 3 months.

1. The bottle is out of warranty
Although there is no data to show what kind of harmful substances will be produced after the expiration of the bottle, there will be potential bacterial hazards in the bottle or outside the bottle after long-term use. Novice parents should remember that, for the sake of the baby's health, they should develop a good habit of replacing the new bottle regularly, usually once every 4-6 months.
2. Cracks on the bottle
If there is a crack in the glass bottle, you need to buy a new bottle for your baby, otherwise it will easily hurt your baby. In addition, if the plastic and stainless steel bottle has scratches, it is also necessary to replace the baby with a new bottle. The scratch is a dead angle of health. Any cleaning method may make the bottle unsanitary. At this time, it will be more stable to replace the new bottle.
3. There is dirt inside the bottle
The dirt in the milk bottle here is not just the "black dirt" we imagined. If the milk bottle is not cleaned thoroughly after long-term milk soaking, it is easy to form a layer of yellow substance under the accumulation of milk dirt, which is also an important "sign" for the baby to replace the new milk bottle.
