If you recall the FUN you had playing in a ball pit as a child, you'll be able to recreate it in your living room. A baby mat like this can be adjusted to create walls as opposed to your standard playmat.  Jumbo mats are made for newborns and infants to lay flat on their stomachs during tummy time. Engaging toys like rattles, animal shaped hanger, & musical hanger are available for playtime. The mesh sides allow older infants to sit safely. This item also converts into a fun, sensory-stimulating ball pit for those busy toddlers.
