Knowledge is power.
When there are more children to a couple the concentration on each of their children can be less. But these days every couple is going for a maximum of two children only. So they have a lot of attachment with them and try to play with them for the maximum possible time.
Taking photographs is very easy these days and everyone will have a smartphone in their hands. So parents take many photographs of their children make digital albums and keep them on their computers or laptops so that the children can see their photos after they grow.
These days I am lucky enough to have sufficient time to play with my three granddaughters and enjoying with them.
