I have an 18mo and we tend to do morning naps too. No idea why but all 3 of my kids have preferred them - if they napped in the afternoon they wouldn't go down until really late at night.
This is our weekday home routine - weekends and nursery days look slightly different but bedtime etc the same.
He wakes approx 7am. Has some breakfast and plays, coming back for cuddles/milk/reassurance on and off until approx 9.30
Then I tend to do some cleaning jobs etc around the house, he follows me around, or we go out, he will start getting tired around 10.30 and I might let him feed to sleep or fall asleep in the buggy. If we are at home I put him down in his cot once he has fallen asleep (unless in buggy then would just leave there).
Wakes up 11.30 - 12ish, he's a bit cuddly after sleep, I make us both lunch. After lunch we might play together or go for a walk.
From around 3pm he plays with TV on, I have computer time because I have an energy dip at this time. Or if big brother needs collecting we leave to do that.
Start making dinner around 4 ready for brother to get back around 4:30, they eat, we try to feed them no later than 5.
After dinner general play/chill time with DH, I might do something like a jigsaw with older one, sometimes run a bath.
Then from 6:30 tidy up / teeth / pyjamas / story and I bring him back into the living room with dimmed lights to feed to sleep. Usually asleep by 715 and I can put him in cot.
During the night he typically wakes around 10pm / 1am / 4am for milk and goes back to sleep. If he's ill/teething/some other complaint it will be more frequent and I bring him into our bed (but trying to be stricter with myself!) - before I started resettling him in his own bed he would wake every 1-2 hours.
I don't change nappy after every wee. Just on waking, before/after nap, and mid afternoon. If he poos I change straight away but disposable nappies can hold a few wees.
