Sleeping with Lovey

Just curious if you noticed a difference in sleep after you introduced a lovey?

When my boy turned 12 months I tried giving him a dino lovey but turns out he has zero interest in dinosaurs 😂. He loves tractors and cars (favorite is a John Deere tractor toy) so I got him a John Deere lovey. Gave it to him tonight and he's been calling it ca-ca. 🥰 Seems to like it and I'm hoping it'll provide him comfort once he's used to it!
