I haven't used this much, and it's been stored at home. Can be used for a long time, from when the baby can sit up to when they start walking! Even after the toddler stage, the soft, fluffy material that babies love can be used like a stuffed animal to play with. It's a backpack type, so it's easy to put on even when the baby is moving around. The elastic belt is adjustable to fit your child's head position. It's covered with fabric, so it's soft and won't hurt. *This type does not have a chest strap.
