Rocking my almost 9 month old to sleep

So my daughter will be 9 months on the 20th and I still rock her to sleep. For naps and before bed. I don’t mind it, but when will she just fall asleep on her own? She’s a walker. She walks around everywhere. I was hoping she’d get tired on her own and just fall asleep anywhere 😂 but that’s not happening.

Anyone going through this? Or has anyone passed this phase?
