TheBoneLock has undergone no testing for use as a safety measure for babies, children, or any other safety use. It works great in normal circumstances as a deterrent for pets and crawling babies under direct parental supervision, but should NEVER be used when safety is a concern. There are many great products out there for safety, please we encourage you to purchase something for that intended purpose. We just want to make lives easier and better for everyone. Stay safe, use wisely.
