Baby bottles must be sterilized in order to kill pathogenic microbes that actively develop in a dairy environment. It is especially necessary to handle dishes in newborns under 4 months of age, during this period the intestinal microflora is still forming in them, and any bacteria can cause severe diarrhea.
For boiling, take a saucepan that will no longer be used for any purpose. Pour water into it and place on the stove until it boils. It is better to take filtered water, tap water contains a lot of chlorine and other harmful impurities.
While the water is boiling, rinse the bottles and teats thoroughly with baby dish detergent. Rinse them thoroughly in clean water, rinse off the detergent thoroughly. To wash bottles, you cannot use soap or other substances with a chemical, and more often toxic, base.
Dip bottles and nipples in boiling water for 10-15 minutes. Over time, remove them with forceps and place them upside down on a clean towel or sterile napkin. You don't need to wipe anything. But remember that after a few boils, the rubber teats will unfortunately deteriorate. Silicone ones last a little longer, but they also quickly deteriorate when exposed to high temperatures.
There are also special bottles that can be sterilized in the microwave. To do this, you need to turn on medium heat and leave the container for a few minutes for processing. Thus, only well-washed bottles can be sterilized.
After 5-6 months of age, the baby can not sterilize the dishes, but simply scald it with boiling water, but be sure to rinse both the nipple and the bottle first. The nipples can be cleaned with table salt; cleaning powders cannot be used.
