I reassure them that I'll call or text if child doesn't settle in but for the most part, I have no transition routine.
I let the parent know ahead of time how I do things and then they drop off their child and let me do my thing. 
This what I do. I'll send a few pics throughout the first few days or couple of text how on how DCK's day is going, but that's pretty much it. I tell new parents it takes 3 weeks for a child to really get used to a change such as new daycare, so don't be surprised if there are random rough mornings/ days after they've "settled in" the first few days.
