I take care of a 16 month old, he almost always eats and naps on a schedule and the rest of the day varies. Here's how it usually goes:
8am: I get to work, he wakes up shortly after and I change his diaper from the night and get him dressed
8:15-9ish make breakfast, feed him, clean up
9-11ish: take him for a morning outing like the park, beach running errands or grocery shopping for the family, story time etc
11ish: get back to the house and feed him lunch, let him play with toys for a bit
11:30ish: give him 4oz of milk, put him in bed for a nap
12-2:30/3: he naps
2:30/3ish: he wakes up and we watch an educational video or play with toys
4ish: second lunch

clean up
4:30ish: take a walk around neighborhood, play outside with sand/water table, play with toys until parents get him home around 6:30
Some days he will take a second nap around 4:30/5 which is great. Best of luck!
