Please help?! Sociology question for group powerpoint presentation

Hi everyone,

I would really appreciate some help on this question i have been stuck on for weeks now, i have a powerpoint presentation on sociological perspectives, the role of family in todays society and the socialisation of children.

the question i am stuck on is:

Analysis of two similarities and two significant differences between contemporary ideas of family and traditional ideas of family using sociological perspectives; changing patterns of family must be considered within your analysis.

I have done the two similarities and 1 of the differences but the other difference i have picked is the difference in sizes between modern and traditional families.

This is what i have so far:

"Sizes of traditional families are larger than modern families. There used to be families of very big size consisting of the members of many generations. The traditional family consisted of grandparents, aunts, uncles, parents and children who commonly lived together. This family group was like a social unit and many times the number of members exceeded over one hundred but in the modern family, a single family system is most common. Now joint families have broken up and their place has been overtaken by single families. Modern families are quite small in size normally consisting of two parents and 1-3 children or even a single parent household with children. Even after children have grown up and got married, they separate themselves from the parental household and establish their own families. Nowadays, in modern families, the number of members rarely exceeds 10 people or so."

i have to relate it to a sociolgical concept and the one that has been chosen for us is socialisation. How do i relate socialisation to family sizes and the changes to family sizes?

any help would be seriously appreciated x
