For babies who have started to sit up unsteadily, and for babies who are just starting to walk and often fall down(^^) This is a fall prevention cushion in the shape of a rabbit. The back view is so cute! It's a backpack type, so it protects the head and back with a cushion. The mesh material is breathable and lightweight, so I think your baby will wear it without feeling uncomfortable. Please note that it will be folded for shipping.
