I think I would note that ALL children nap after lunch (list your time if it is set) and children under the age of 18months are given the opportunity to nap for 20-30minutes before 9am (in stroller/car while out and in bed when at the house).
Anyone that asks, just note that in order to keep all children on the same afternoon nap schedule (which is needed to allow time to cook/clean/disinfect) you allow a short cat nap in the morning for the youngest children while they adapt to a one nap schedule.
Morning nap is NOT there to make up for being up all night it is just there to hold the kids over until nap time. The parents will need to do their part to ensure the little ones are getting a solid nights sleep.
