How should I prepare my Philips Avent Natural Bottle and Nipple for first use?
Thoroughly clean all parts before the first and each subsequent use to ensure good hygiene. After each feeding, disassemble all parts and wash them in warm, soapy water, ensuring that any food residues are removed before rinsing thoroughly. If you use a brush to clean the tip of the feeding nipple, clean it as carefully as possible to avoid damage.
Sterilize the cleaned parts using a Philips Avent sterilizer, or boil them in water for 5 minutes.
