This is a deer-shaped backpack cushion to prevent babies from bumping their heads. The shoulder straps are adjustable to accommodate growth. The inside is made of mesh material suitable for hot seasons, and it is lightweight and breathable, preventing stuffiness. My child didn't fall backward much, so I hardly used it, and it's in near-mint condition. You can buy it immediately, so please feel free to purchase it ♡ I also have other child-related items for sale. Please take a look if you'd like ♡ I'll offer a discount for combined purchases. →#zousan'sChildRelatedItems♡
