Hot formula can easily burn your baby's mouth or tongue. It is best to heat a bottle by placing it in a container of warm water. If you do use a microwave, shake the baby's bottle to make sure the liquid is evenly heated. Always test the formula by dripping a little on the inside of your wrist. It should feel lukewarm.
Overheated bottles can explode.
Loosen the lid. Then tighten it before giving the bottle to your child. Check the temperature of the hot water that comes from your taps. If your water temperature is more than 49 C, call the company that provides the fuel to heat your water. Gas, electric and oil companies will re-set the temperatures on hot water heaters.
