Jolly Jumper Head Hugger 3-in-1 provides head and neck support for infants and babies. The 2-stage Head Hugger is designed to grow with your baby, from newborn to infant. As your infant grows, remove the inner Head Hugger that was designed for newborns, leaving the other Head Hugger in place. When baby no longer requires neck/head support, remove both. Soft Straps, (included) are made of soft chenille fabric to prevent the car seat straps from chafing soft little necks.
