How to Sterilize Baby Bottles Correctly: Step-by-Step Guide | Pediatrician Advice

Dr. Sandip Gupta

This video explains why sterilizing baby bottles is important and provides a complete step-by-step guide to sterilizing, drying, assembling, and storing them safely. What is covered in this video: Why sterilizing bottles is important: A newborn's and a baby under 3 months' immune system is not fully developed. Sterilization kills bacteria and viruses, protecting the baby from diarrhea (loose motions), vomiting, and serious stomach infections. Step-by-step sterilization process: Preparation (gather materials): Keep the bottle, nipple, cap, a large pot (or electric sterilizer), tongs, and a clean bottle rack or paper towel for drying ready. Disassemble and clean: Wash your hands well and open all parts of the bottle (nipple, ring, cap) separately so no milk residue remains anywhere. Rinsing: Wash all parts thoroughly with cold/clean water. 2 main sterilization methods: Boiling method: Take water in a large pot and fully submerge all bottle parts (no air bubbles should remain inside). Once the water boils, let it boil well for at least 5 minutes. Remove with tongs or clean hands and dry. Electric/specialized bottle sterilizer: Add water as per the manufacturer's instructions, set the bottles, and remove them with tongs once the cycle completes. Drying, assembling, and storing: Let sterilized parts cool and dry on a clean rack or paper towel, then assemble with clean hands. Store bottles clean and covered; to avoid recontamination, don't touch the inside of the bottle or the tip of the nipple directly with your hands.
