When Mary Weld visited Dugan's Alleys to participate in the weekly bowling league competition held there, she brought her twoyear-old son, Bobby, along and left him in a nursery provided by Dugan for the convenience of his customers. The children in the nursery were normally supervised by three attendants, but at this particular time, as Mary Weld knew, there was only one attendant present to care for about 20 children of assorted ages. About 30 minutes later, while the attendant was looking the other way, Bobby suddenly started to cry. The attendant found him lying on his back, picked him up, and called his mother. It was later discovered that Bobby had suffered a skull fracture. If a claim is asserted against Dugan on Bobby's behalf, will Bobby prevail? 
Yes, because Dugan owed the child the highest degree of care.  Yes, because a tw0-year-old is incapable of contributory negligence.  No, unless Dugan or his employees failed to exercise reasonable care to assure Bobby's safety.  No, if Mary Weld assumed the risk by leaving Bobby in the nursery
