I do the "my day at daycare" sheets. I hate doing them but the parents love them. I always add a note at the bottom about something xxxx did that was cute, or said or an achievement. The parents are addicted to these little notes. I have a couple of Mom's that save them in a binder and another that should she forget hers comes back for it! My husband just shakes his head at me as I growl doing them. He tells me I have only myself to blame having added the comments.
I've started doing these in Word Format (I just adjust the details throughout the day) & just before pickup I email them off. I try to minimize what the parent has to bring/take home other than the child.
Children are great imitators.
So give them something great to imitate.
