I mention all the readiness stuff at the interview but I also email the parents one month before care (for the 12 mos olds I sign on early) and check in re: the readiness stuff. I will ask specific questions e.g. "how's Mike doing with the sippy cup?" "is he soothing himself to sleep yet?" etc. This has helped tremendously and has helped parents I think feel connected to me and to the daycare before their child starts.
