Do you need a bottle sterilizer? What the CDC and AAP say (2026)
Short answer: usually no. The CDC says to clean bottle parts after every feeding, and if your dishwasher uses hot water and a heated drying (or sanitize) cycle, no separate sanitizing step is needed. Sanitize at least daily if your baby is under 2 months, was born preterm or has a weakened immune system; boiling for 5 minutes works as well as a gadget. If you own a Baby Brezza SuperFast Sterilizer Dryer, check the November 5, 2026 recall.
Recalls checked November 10, 2026 on CPSC. We searched CPSC recalls with “sterilizer” and “Brezza” in the title announced since November 1, 2025 and found one: Baby Brezza SuperFast Sterilizer Dryer (November 5, 2026; models BRZ0083, BRZ0154 and BRZ0156; about 29,000 sold in the US). The units can overheat when plugged in, posing a burn hazard. Stop using it and contact Baby Brezza for a free replacement. Our recall-check policy.

Sterilizers are a common registry item. The CDC’s[1][4] guidance treats sanitizing as an extra step on top of cleaning, and lists boiling, steaming and bleach as equal options.
When does sanitizing matter?
| Your situation | What the CDC/AAP say |
|---|---|
| Every family, every feed | Clean bottle parts after each feeding: dishwasher, or hand-wash in a basin used only for feeding items, then air-dry (CDC) |
| Dishwasher with hot water and heated dry or sanitize setting | No separate sanitizing step needed (CDC) |
| Baby under 2 months, preterm or weakened immune system | Sanitize at least once a day (CDC) |
| Older, healthy baby, hand-washing carefully | Daily sanitizing may not be necessary (CDC) |
Free ways to sanitize
The CDC[1][4] lists three equal options, after cleaning: boil parts in water for 5 minutes; steam in a microwave or plug-in steam system following the maker’s directions; or soak in bleach solution (2 teaspoons of unscented bleach per gallon of water) for at least 2 minutes, then air-dry without rinsing. The AAP[2][3][5] adds that a dishwasher with heated water and a hot drying cycle can stand in for boiling. Let everything air-dry on a clean towel; don’t rub dry with a dish towel (CDC).
Who should skip this, and what to skip
Families with a dishwasher that has hot water and heated dry, and parents of older, healthy babies, can generally skip a dedicated sterilizer. A sterilizer can save time for parents of a newborn or preemie who sanitize daily and don’t have such a dishwasher.
- Buying a sterilizer “because you have to”: The CDC[1][4] lists boiling and a hot dishwasher as equal options.
- A recalled Baby Brezza SuperFast Sterilizer Dryer: CPSC[6]: overheating and burn hazard (November 2026).
- Washing bottles directly in the sink: The CDC[1][4] and AAP[2][3][5] advise a separate basin, since sinks and drains carry germs.
- Sanitizing parts that aren’t clean yet: The CDC[1][4] says sanitize only after cleaning.

How to prepare baby formula safely: water, mixing and storage (2026)
Short answer: use safe water (most tap water is fine), measure exactly with the can’s scoop, add powder to water and shake in the bottle, and never add extra water. Use a bottle within 1 hour of starting a feed and toss leftovers; refrigerate unused prepared formula and use it within 24 hours. For babies under 3 months, preterm or immune-compromised, the CDC suggests ready-to-feed liquid or mixing powder with water hot enough to kill germs.
guideDo you need a bottle warmer or formula maker? (2026)
Short answer: neither is required. The AAP says a bottle made with room-temperature tap water right before feeding needs no warming, and a bottle can be warmed under warm running water or in a container of warm water. Never microwave a bottle (AAP; CDC). A formula maker is fine only if it measures exactly and you keep it scrupulously clean; it can’t change the 1-hour, 24-hour or extra-caution rules for young babies.
guideHow to choose a breast pump: types, used pumps and cleaning (2026)
Short answer: check your insurance first, since most plans must cover a pump (rental or one you keep). Choose by how often you’ll pump: a manual pump for occasional use, a powered double pump for regular pumping or work. Don’t buy, borrow or share a used single-user pump; the FDA says it can’t be reliably cleaned between people. “Hospital grade” isn’t an FDA term.
guideAre plastic baby bottles safe? BPA, glass and choosing bottles (2026)
Short answer: yes. The FDA amended its rules in July 2012 so BPA-based polycarbonate is no longer provided for in baby bottles and sippy cups, because makers had abandoned it. The AAP’s precautions: avoid old clear bottles marked #7 or “PC”, don’t microwave plastic or heat it in the dishwasher if it’s polycarbonate, and consider glass if you can handle the breakage risk. The AAP says bottle type matters less than how you hold your baby.
guideHow to store breast milk: times, thawing and travel (2026)
Short answer: the CDC’s rule is 4 hours at room temperature (77°F or colder), 4 days in the refrigerator, and about 6 months in the freezer, with up to 12 months acceptable. Thawed milk: use within 24 hours in the fridge and within 2 hours once warmed, and never refreeze it. Never microwave breast milk. Store in 2–4 ounce portions at the back of the fridge or freezer, not the door.
