It is not uncommon for young children to explore and become curious about their environment, including doors. If you are concerned about your child’s safety, there are a few things you can do to prevent them from opening the door on their own. One option is to install a childproof lock or doorknob cover on the door. You can also use a gate to block off the area around the door, or train your child to stay away from the door by using positive reinforcement techniques. Additionally, you can supervise your child more closely, or install a baby monitor to keep an eye on them from another room.
