Prep formula ahead of time

Salma

So I really want to prep my babies bottles after each feeding because he wakes up and wants to eat right away. I don’t have a chance to let the formula sit for a bit so the air bubbles go away. So, that’s why I want to have it prep ahead of time, so it has no air. I know, it supposed to be tossed after an 1 hour of sitting in room temperature so it’s doesn’t form bacteria. But, is this really true?

Help!

Who preps bottles ahead of time?
