took out of package to wash before my daughter was born, but never used Boppy Head And Neck Support, Pink Stripe Flowers Reversible Fabric, With Removable Neck Support, For 3- or 5-point Harness systems, For Strollers And Swings, 0+ Months This head support is easy to install and works with both 3- and 5-point harness systems so baby can enjoy support in many seats. The Boppy Head and Neck Support was built to last. The removable neck ring allows you to change support as baby grows. Remove the neck support as baby gains strength or when neck support is not needed. The reversible design gives you options with a super-soft knit on one side and cooling mesh on the other so you can change with the weather. Machine washable. Recommended age 0+ months. Boppy Head and Neck Supports are for awake-time support in strollers, bouncers, and swings. Not for car seats. Do not use for sleep. Why we say "No Car Seats": Boppy puts your family first. When a car seat insert is needed, the car seat manufacturer will usually provide one. The inserts provided with your car seat are designed specifically for that car seat. Always be sure to check your product warranty information when adding accessories like a head support.
