When we deal with mixed ages and are the only adult on staff so to speak it is hard to be in several places at once. Properly greeting a parent/child at the door, helping a toddler with the daily craft or just about to finish snack as a child arrives only to find out he is hungry because he has been up for a couple hours but they just didn't bother coming - guess who is really hungry by lunchtime because we just move on to next event. The not feeling appreciated is caused by the staggered arrivals because it can make the caregiver feel that the effort they put in to planning the craft, snack or lesson wasn't important enough to the family to get the child there in time to be a part of what we planned for them.
