My youngest has always been an early riser. It's a miracle if she sleeps until 6:30 and she's 7 yo. Now I'm the one waking up at 5:45/6:00 on a Saturday morning because that's my internal clock. Even if she's still in bed.

Single mom here. I used to look forward to the day when my kid slept in. He is 14 now and can sleep until noon so yes, the time will come. He started sleeping later around age 10 or so.
