Web alarm clock for 5:00 a.m.
As you hand the school-ceremony drop-off to another adult, set the alarm for 5:00 am so the changeover happens without a rushed knock or message. Confirm who will wake the child, prepare the uniform, and handle the ride, then leave any school gate details where they can be checked quickly.
Your handover may fail quietly if the phone or tablet is on silent, so test whether this browser alarm can be heard at the volume you expect. Choose 5:00 am, start the alarm, and keep the page active while you finish the remaining arrangements. If the page is closed or the device goes to sleep, the school-ceremony alarm may not sound, leaving the other adult without the agreed signal.
Because the household is moving before sunrise, build a small buffer between waking and departure instead of using every minute for preparation. Place the uniform, ID, water, and bag together the night before, and agree on a leave-by time that allows for early traffic near the school. That reserve also protects the next commitment later in the day: a delayed ceremony or a longer drive will not immediately push everything else behind.
