Also, I am somewhat understanding of lateness due to snowstorms, etc. Mostly, I find the parents leave early enough that they do get here on time...but I have actually told all of them that I do understand if there is a major weather event and they get stuck in traffic. The last thing I want is them driving crazy to get here on time and possibly causing an accident. They usually call me to let me know they are stuck, but on their way and I am relaxed about that. I guess it's because I don't have habitually late parents, so I know that in the event of bad weather, it happens. I have also been the parent stuck in a storm trying ot get to daycare to pick up my child...it was so stressful!
