What happens if you don't sterilise baby bottle?
Not sterilising your baby's bottles will allow bacteria to develop on the feeding equipment. This may lead to infections including diarrhoea and vomiting1.
The CDC notes that Cronobacter germs can contaminate dry, powdered foods, such as infant formula and, subsequently, baby bottles. This type of bacteria can cause a very rare but potentially life-threatening blood infection called sepsis, particularly in infants.
For extra germ removal, sanitize feeding items at least once daily. Sanitizing is particularly important when your baby is younger than 2 months, was born prematurely, or has a weakened immune system.
Before the first use, sterilize nipples and bottles in boiling water for 5 minutes. After that, you don't have to sterilize your baby's bottles and supplies each time you feed your baby. Do wash bottles and nipples in hot, soapy water (or in the dishwasher) after every use.
Water that hasn't been boiled can also contain bacteria. Formula therefore needs to be made up with water hot enough to kill the bacteria, which is at least 70 degrees C. This means boiling the kettle and leaving it to cool for no longer than 30 minutes, so that it remains at a temperature of at least 70 degrees C.
It's recommended that you wait until your baby is at least 12 months old before you phase out sterilizing.

The exact amount of protection that a baby receives from its mother depends on the antibodies that the mother has in her immune system. Research indicates that a baby's passive immunity lasts for around six months. One study examined the passive immunity to measles in infants.
According to most pediatric health experts, infants can be taken out in public or outside right away as long as parents follow some basic safety precautions. There's no need to wait until 6 weeks or 2 months of age. Getting out, and in particular, getting outside in nature, is good for parents and babies.
Breastfed babies have fewer infections and hospitalizations than formula-fed infants. During breastfeeding, antibodies and other germ-fighting factors pass from a mother to her baby and strengthen the immune system. This helps lower a baby's chances of getting many infections, including: ear infections.
