Newborn formula preparation?

When preparing newborn formula, hygiene is the most critical point. Wash your hands with soap, always sterilize the bottle and nipple you'll use for formula. Let boiled tap water cool to 70°C (about 30 minutes) — this temperature is enough to kill any possible bacteria in powder formula. First pour water into the bottle, then add the measured powder according to manufacturer's instructions (don't add too much or too little). Shake well, cool to body temperature by running under cold water or placing in a bowl of cold water. Don't keep prepared formula at room temperature for more than 1 hour or in the refrigerator for more than 24 hours. Don't reheat and reuse leftover formula.
