Help with sleep schedule please

My son is turning 1 year old on June 15th

The lat two days he doesn’t want to take his second nap I keep trying for at least one hour and he won’t take it

First night ( without taking his last nap) he was in bed and sleeping at 8:20 and woke up at 8:15 am

Yesterday ( second night without taking his last nap) he was in bed and sleeping at 8:30 and woke up at 3:45 am!

How do I fix today? So he can go back to his regular schedule?

Today he woke up at 10am

What do I do?

How many naps today?

Thank you very much in advance
