You only boil nipples and bottles once. And that is before use to sterilize them. Every other time just use dish soap and a bottle brush and let them dry like every other dish in your house
Do u boil the nipples as well?
Warm water and soap. With a bottle brush. Or put a big pot of water on the stove until warm the put the bottles in with soap let stand for about two min brush and rinse. Let stand upside down on towels for ten min to dry
A good trick my mom taught me that works better than the bottle cleaners is put a lil soap a lil hot water and like a big pinch of rice n close n shake works great!
