Family life and the structure of this was changing over time; according to the videos.
The first video shows the typical family in the 70´s, for example my father´s family. They were a large blended family: eleven brothers and sisters and my grandparents.
Right now isn´t possible because of the rhythm of life: parents work every day, children go to school and activities on the afternoon but the parents haven´t have time to spend with them.
For this reason, I mean, people have one or two children (in the best case) to be able to work and spend time with them, is not easy.
Perhaps if the government eases schedules and invest money to enchance increase birth rate could be exist the large blended families, they were more fanny than the little.
