The family... In the past, families were large, for example my grandparents (on the part of my mom) they had 8 children, although in those days it was a small family in México. Now families tend to be small and people usually have one or two children, they are very rare people who have more than 3 children nowadays. Before, the children spent more time with their parents, at least with their moms. Now parents rarely are with their children and they both have to work to be able to keep them, therefore they leave their children alone or with a family member to take care of them, but it is not the same. I think in the past the children had a better feeding because everything was natural, their mothers cooked everything they ate. In these days the children eat a lot of junk food like cakes, pizzas, hamburgers, etc. That causes problems of obesity in children.
