One day shortly after the birth of their new baby, the mother had to go out to do some errands. So the proud papa stayed home to watch his wonderful new son. Soon after the mother left, the baby started to cry. The father did everything he could think of to do but the baby wouldn't stop crying. Finally, the dad got so worried he decided to take the infant to the doctor. After the doctor listened to the father all that he had done to get the baby to stop crying, the doctor began to examine the baby's ears, chest and then down to the diaper area. When he undid the diaper, he finds that the diaper is indeed full. "Here's the problem", the Dr. says. "He needs a change." The father is very perplexed, " But the diaper package says it is good for up to 10 lbs!"
