When do baby bottles need to be sterilized?
For newborns and infants up to 3-6 months, it is recommended that baby bottles be sterilized after each use. As the child gets older, their immune system strengthens and you can switch to washing the bottle with hot water and dishwashing liquid, just like you wash everything else. However, you should still sterilize the bottles 1-2 times a week. If you buy new bottles, they should be sterilized before the first use and you can also do this during periods of illness and when traveling. If you prepare formula by hand, remember to also keep the measuring cup you use for dosing clean.
Methods for sterilizing baby bottles
There are several effective methods for sterilizing baby bottles:
- Boiling: A classic and reliable method that requires minimal equipment. Disassemble the bottle and boil for five minutes.
- Steam sterilization: There are several models of sterilizers that sterilize bottles with steam. Fast and effective, but the cost can be a disadvantage.
- In the microwave: Some sterilizers can be used in the microwave.
