DD's had a stuffed animal connected to a small blankie toy and her sleep sack since about 6 months old.
She's had a regular, thin pillow since 13 months old.
And she's had a blanket (not a comforter, just a blanket) since about 15 months old.

blanket since she was about 3 months old .. pillow for the last 6 months.
she sleeps w/ a blankie, its her lovey.
blankie, light one now, the weather has been warming up, she loves a fluffy one to rub her in her face and most of the time she holds it to sleep.
we are trying to make her sleep with a pillow between her legs, although it lasts for some minutes, we want to create her the habit.
Mia's always had a blanket in her bed (yes, I know the risks...it was literally the only way we could keep her warm enough in our house). Ben has had an open weave crocheted blanket since about 4 months in his crib.
I don't know when/if we'll add a pillow.
