Yes, you absolutely must wash baby bottles thoroughly with hot, soapy water and a bottle brush to remove all milk residue before sterilizing them, as sterilization kills germs but doesn't remove milk, which feeds bacteria; washing gets rid of milk, while sterilizing kills remaining germs for your baby's protection, especially for newborns.
You absolutely have to wash before sterilizing. Even if you don't sterilize they need to be washed. The soap from washing gets rid of the leftover milk/formula and takes away a lot of the germs. Sterilizing uses hot steam to kill a lot of the germs leftover after washing (it's not 100%).
I find its best to wash the bottles, nipples and everything and then put it into the sterilizer.
Do you have to sterilize baby bottles? Yes, sterilizing is recommended for newborns, preemies and when water quality is uncertain. After the first use, washing with hot water and soap is usually sufficient for healthy babies with access to clean water.
Sterilize after traveling with the bottle. Sterilize if milk or formula has been inside at room temperature beyond the recommended time period. Sterilize if it comes in contact with contaminated surfaces or floors. Sterilize daily when baby is sick with the flu or other viral or bacterial infections.
It's important that there aren't any air bubbles trapped in the bottles and teats when they're under the water as this will stop them being properly sterilised. Most cold water sterilisers have a cover to make sure the bottles and teats are kept under water . After sterlising, rinse the bottles with cool boiled water.
The "2-hour bottle rule" for baby formula means prepared formula should be used within 2 hours at room temperature, or within 1 hour of starting a feeding, to prevent rapid bacterial growth, as bacteria from the baby's mouth can contaminate it. If not used within the time limit, discard leftovers; if feeding doesn't start within 2 hours, refrigerate and use within 24 hours, but never refreeze, and always discard any leftover milk after feeding.
The solution is effective for 24 hours and there is no need to rinse baby items bafore they go into baby's mouth. Use to sterilise all breastfeeding equipment and baby feeding accessories: breast pump parts, baby bottles, soothers, teething rings, small plastic toys, plastic cutlery and weaning items.
All bottles and the formula pitcher and breast pumps, etc. are washed with hot water and soap and then sterilized. Equipment is washed usually a couple of times a day and sterilized immediately after.
Hand sanitizer is more precise at killing bacteria and most viruses, but hand washing can effectively remove all dirt, microbes and chemicals on the hands.
Ensure items are clean before sterilizing.
Sometimes bottles, parts, and other items can have left-over food stuck on them. Ensure the items to be sterilized are clean and empty before putting them in the sterilizer.
Sterilising by boiling
Signs Your Steriliser Needs Descaling
You should sterilize baby bottles every day. If you don't have a bottle sterilizer, you can do this by boiling them in water for five minutes, using a microwave steaming tool, or putting them in the dishwasher if they're dishwasher-safe.
You may see products with alternative methods to sterilise bottles and equipment such as ultraviolet (UV) sterilisation. We would not recommend these products or methods. They can be ineffective at sterilisation and potentially dangerous to both you and your baby.
As your baby grows, their immune system gets stronger, and eventually, you'll no longer need to sterilize their feeding equipment. It's recommended that you wait until your baby is at least 12 months old before you phase out sterilizing.
Before sterilising, you need to: Clean bottles, teats and other feeding equipment in hot, soapy water as soon as possible after feeds. Use a clean bottle brush to clean bottles (only use this brush for cleaning bottles), and a small teat brush to clean the inside of teats.
Germ-Free Goodness: Sterilizing doesn't just clean; it ensures that harmful germs, mold, and mildew are effectively removed from your baby's products, offering a level of cleanliness that regular washing can't achieve.
After washing baby bottles with hot soapy tap water or filtered water, sterilize them using methods such as boiling, steam sterilizers, or chemical sterilants. This ensures maximum safety by eliminating any remaining bacteria or contaminants that could harm your baby.
Milton sterilising fluid is a form of diluted bleach, containing 2 percent sodium hypochlorite. It can be bought in most supermarkets and pharmacies. Milton baths use a gentle mixture of diluted bleach and water, very similar to the chlorine used in swimming pools.
It is therefore totally safe for babies and can be applied directly to the skin - even swallowed - without harm. Milton Sterilising Fluid is used for sterilising breast feeding equipment and all babies feeding utensils, including bottles, soothers, teething rings, small plastic toys and weaning items.
Milton Antibacterial Surface Wipes clean and disinfect baby accessories and equipment, including soothers and teats with no need to rinse: highchairs, toys, changing mats, potties, baby baths, kitchen, work tops, door handles, phones, car, etc. Ideal for quick cleans up at home and on the go.
The 5-3-3 feeding rule is a baby sleep training strategy to encourage longer stretches of night sleep by delaying feeds: don't feed before 5 hours after bedtime, then feed, then wait 3 hours for the next feed, and another 3 hours for the next, using other sleep training methods (like Ferber or CIO) for wakes outside these windows. It's for older babies (not newborns) and aims to reduce night feedings by establishing a routine, but flexibility is key, and you should always prioritize your baby's hunger cues and consult a doctor.
At 1 month old, babies usually eat roughly every 2 - 3 hours. Breastfed babies typically eat more often than formula-fed babies since breast milk digests faster than formula [2]. Newborns at this age will eat about 2 - 4 ounces at each feeding with roughly 8 - 12 feedings in a 24-hour period.
When fed too much, a baby may also swallow air. This can produce gas, increase discomfort in the belly, and lead to crying. An overfed baby also may spit up more than usual and have loose stools. Although crying from discomfort is not colic , it can make crying more frequent and more intense in an already colicky baby.
