Has anyones 9 month old used a pillow?

Curious if anyone has used a pillow with their 9 month old. I do not use a pillow while they’re sleeping in their crib but when he takes naps in my bed he loves to snuggle up and lay on my pillow and he sleeps so much better with a pillow. I am curious to see if anyone has used a pillow before 1 years old.
