- Glass bottles are one of the safest options in such cases as they can withstand higher temperatures compared to plastic bottles. But the bottle can crack and break easily if it falls down.
- Ensure that the equipment you use during the sterilization process like water, towel, tongs, container, etc. are clean.
- Keep the hot water container, steamers, and other high temperature apparatus away from your children grasps to avoid accidents. Hot steam can cause burns as easily as boiling water.
- If you have chemical tablets, liquids, bleach, or any other chemicals, then keep them far away from your children’s reach.
- Washing your hands before you handle the sterilized feeding equipment is a must to ensure a germ-free environment.
