Do I need to add anything for support?

calm down

Will this support a newborn's head or do I need to add something to it? I've heard that adding things are not safe, but I also heard that if the baby's head needs support the nurses will add rolls of towels. So I'm thinking if towels are okay, then adding a head support should be fine too? I dont want her head flopping around on the way home from the hospital. I havent done much research on it yet, but plan to google tomorrow. I'm 36 weeks pregnant; we packed our hospital bag today and are getting the carseat ready tomorrow.

Someone bought me this for my baby shower. I'm not sure about using it yet or not.
