Prepared infant formula can spoil if it is left out at room temperature.
Once you mix water and formula powder to create that magical elixir that nourishes your sweet babe the countdown clock starts ticking.
After you boil the water allow it some time to cool down before you mix it with the formula powder and feed it to your baby.
Use prepared infant formula within 2 hours of preparation and within one hour from when feeding begins.
You will learn the temperature your baby prefers shortly as some babies like their bottles warmer.
Either way as long as your baby is happy and eating well there s no reason to be concerned if she prefers cold or warm formula.
It s fine to give your baby room temperature or even cold formula.
Throw away formula your baby didn t finish.
If you do not start to use the prepared infant formula within 2 hours immediately store the bottle in the fridge and use it within 24 hours.
The formula should feel lukewarm not hot.
In contrast others prefer them cooler and even cold.
If your baby prefers warm formula place a filled bottle in a bowl of warm water and let it stand for a few minutes or warm the bottle under running water.
Some babies prefer warm formula and others are fine with cold formula.
