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. 
Same here. I think having a parent stick around makes it harder for the child to adjust. Plus it throws off my routine with the other kids. I don't mind being flexible when I need to be, but I really love my routine.
