Data from Statistics Canada published in 2017 showed that Generation Z comprised 17.6% of the Canadian population. According to Statistics Canada, between 1980 and 2009, the frequency of the sudden infant death syndrome (SIDS) dropped from one per a thousand live births to 0.3, a 71% reduction. Data from the United Nations shows that the mortality rate of newborns between 28 and 364 days of age plummeted 64% and that of toddlers below the age of five fell 9.7% between 1980 and 2015. According to Statistics Canada, the number of households with both grandparents and grandchildren remained rare but has been growing. In 2011, five percent of Canadian children below the age of ten lived with a grandparent, up from 3.3% in the previous decade. This is in part because Canadian parents in early twenty-first century cannot (or think they cannot) afford childcare and often find themselves having to work long hours or irregular shifts. Meanwhile, many grandparents struggle to keep up with their highly active grandchildren on a regular basis due to their age. Between grandparents and parents, potential sources of friction include the diets of the children, their sleep schedule, how to discipline them, and how they may use electronic gadgets. Parents today are more reliant on the Internet for information than their own parents, and many even recommend that they take grandparenting classes. Because Millennials and members of Generation X tend to have fewer children than their parents the Baby Boomers, each child typically receives more attention his or her grandparents and parents compared to previous generations.
