Parents really do suffer from a lot of paranoia when it comes to their children. There is not a lot that they can do when it comes to their children's safety and they have to ensure that everything is under check from the limited capacity that they have. Some parents try their best to keep away the impact of small things such as children locking themselves inside doors.
Children often do get themselves in a tangle and getting themselves locked inside a room can be a hassle at times. One thing that can be done here is to use rubber bands on your locks to make them safe. Position the rubber bands in a way that covers the lock as a whole, so that there is no room for error left for children to lock themselves in.
