Common Mistakes to Avoid

1. Insufficient Cleaning

Reason: Not scrubbing all parts thoroughly, especially the nipple and ring, can leave milk residue and bacteria.
Solution: Use a bottle brush with a long neck to reach all areas and ensure complete removal of residue.

2. Incorrect Sterilization Method

Reason: Using the wrong temperature or time for sterilization (e.g., boiling for too short a time, or using a dishwasher on the wrong setting) can leave harmful bacteria.
Solution: Always follow the manufacturer's instructions for sterilizing your specific bottles and ensure proper time and temperature are met.

3. Reusing Sterilized Bottles Too Late

Reason: Leaving sterilized bottles in a container for too long before use can introduce new bacteria from the air.
Solution: Use sterilized bottles immediately or store them in a clean, dry, and airtight container for no more than 24 hours.

FAQs
