How would you sterilize baby bottles? Using the conventional Way of boiling water or using a UV Ray sterilizer? What is the difference? #parenttown

I usually sterilized my baby bottles in a boiling water. Just buy a pot that all fits the bottles and boiled it for 10-15 mins, i guess. That way it’s inexpensive than to buy an expensive one. Children are grown fast and later on, you just realize that you don’t need the bottles for them anymore.
