10 month old wakes quietly

My 10 month old was sleep trained at about 6 months. She falls asleep independently for night and naps and is currently on 3/3.5/4 Lately I’ve suspected she’s awake before I wake up, but quietly. I paid for my cam subscription and this morning noticed she woke up at 6:30am and just sat there, rolled around, sat and stood quietly for about an hour. It’s 7:30am now and she’s still awake but just laying there silently.

At what point do you get her up for the day when you notice??
