A lovey is any object that a baby or toddler bonds with in order to feel comforted and secure, aka a security blanket.
Before use, mom or dad can wear the lovey around to help it smell like the parent, which increases its effectiveness in bringing comfort to your little one. This is a great idea for a carseat, to hold while nursing or feeding baby. They are 14in x 14in spread out, which makes them a perfect size to throw in a diaper bag or for travel. The soft 100% Cotton gauze is the same fabric as Ellie + Layne's blankets and is great comfort as baby grows.
Loveys can be safely introduced as a sleep tool after 12 months per the American Pediatric Association guidelines, otherwise a lovey should only be used in supervised situations to prevent accidental suffocation.
