I use a daily email communication instead. I do one group email to all parents telling a little about our day (I do not include nap lengths, how much kids ate, etc.). Antyhing personal that needs to be communicated is either sent in a separate email or told to parents at the door. I find the parents really appreciate the daily email and love knowing what their kids are doing all day. It helps them feel connected, epecially when the kids are too young to tell them about it themselves. I don't find times of naps, amounts eaten, etc to be especially important unless there is something unusual such as an extra long nap or a child who normally eats well and does not...then I usually tell them at the door.
