The family...

In the past, families were large. For example, my grandparents (on my mom's side) had eight children, although in those days it was actually considered to be a small family in México. Currently, families tend to be small and people usually have just one or two children. Few people have more than three children nowadays. In the past, children spent more time with their parents, at least with their mothers. Parents are with their children less often now and they both have to work to be able to support them. They leave their children alone or with a family member to take care of them; it is not the same. Before these changes, children had better nutrition because everything was natural and their mothers cooked everything they ate. Now children eat a lot of junk food like cakes, pizzas, hamburgers, etc. that leads to obesity, a major health problem for children.
