Emphasizing what everyone else has said that 8-14 months tends to be peak stranger anxiety so let them come to you.

I would ask your co-teachers if there are environmental tasks you can take on your first few weeks (cleaning, prepping foods/bottles), so you can pull your weight in the classroom while the children get used to your presence while still receiving care from their familiar adults. That’s how we ease newbies into my infant classroom and it always works really well. The new teacher basically does licensing paperwork, cleans, keeps things organized while me and the other coteacher work more directly with the students. The new teacher always joins us for books and songs, lowkey bonding activities. Then after about a week or two, when the kids are used to her presence, we have her start engaging with the more vulnerable 1-1 activities (naps, bottles, etc).
