Day Care job tips?!?!

I just got a job at a daycare and I will be starting sometime next week. They said I will be watching 11 (6 week-1 and a half year olds). I’m not a mom but I have plenty of patience and I LOVE kids. I have two nephews and a niece that I babysit from time to time but I’m so nervous cause this is going to be 11 kids at once. Im scared I’m not gonna know what to do when each baby starts crying 😭☹️
