If you want to use the cradle outside of your home - or like to have your baby with you at all times - a door clip is an excellent idea. If your baby also finds it particularly easy to rest in the bassinet, you'll probably want to bring it with you to a mother's group or to visit the grandparents. The door clip is particularly ideal here.
If you want to use the door bracket with a spring cradle and motor, you must have at least 220cm of space from the top of the door frame to the floor.
