Last week, your neighbors told you that their 18-month-old son has been sleeping through the night for the past two months. They were very happy about this new development and were looking forward to many more months of a good night's sleep. This week, however, they say their son has started waking up at night and has been pretty fussy during the day. What is the likely reason for this waking and fussing?

even though there may be variations in human emotions over time, the poem “ a contribution to statistics” by wislawa symborska suggests that the only unchangeable characteristic is mortality.
