In tort law, the doctrine that one who has a dangerous condition or thing on his property that is likely to attract a curious child is under a duty to take reasonable steps to protect the child from it. For example, one has a duty to fence or cover an unsupervised swimming pool. The fact that the child is a trespasser does not negate the duty, but is one of many factors to be taken into account in determining the exact extent of the property owner’s duty and the level of care required of him.
