Sterilizing by boiling

Also see to it that the bottles/feeding equipment you use, are safe enough to be sterilized by boiling method. While using the boiling method to sterilize the baby bottle, the teats tend to get damaged faster than usual. So keep the regularly check that teats and bottles are not torn, cracked or damaged. Just like any other method of sterilizing, just detach all parts of baby feeding bottle, and wash them with water or soapy solution. Wash them once again under cold running water, leaving no traces of baby detergent. Take a wide mouthed vessel, in fact dedicate one vessel exclusively for sterilizing your lo’s baby bottles. Fill the vessel almost 75-80%, and boil it for at least 10-15 minutes. Switch off the stove/gas, put the baby bottles and its attachments, and see to it that they are fully submerged. Take a clean lid and close it. Meanwhile wash your hands clean the surface or the drying racks where you will put all bottles and it’s attachments to air-dry. If the bottles are not being used immediately, they should be put into the racks, air dried and assembles together fully with the teat and lid in place. This will prevent the sterilized bottle from being contaminated, along with the inside and outside of the teat, with covering bottle cap.
