Having been somewhat blissfully ignorant of what a blog actually is I enquired of my (computer whizz) son, who regularly functions as my I.T. advisor/consultant.
He assured me that it is simply a means for people with an over-inflated sense of self-importance to show off and attempt to gain the attention of others!

It didn't really feel like something I was needing(!) - but I suppose it is always acceptable for a new nana to brag about her grandchild! - So, let's see how we go!
