Running commentary of life?

Looks like a new form of parenting has crept into our society. The little one, usually a toddler would be given sort of of a running commentary of all the things that go around him.

Bring him to a checkout counter, while the mother is busy unloading the trolley of food stuff, the father would be busy narrating what is being done and how the transaction is recorded, calculated and so forth.

At the obstetrician's office, whilst having the good doctor examine the yet-to-be-born addition to family, father does his duty again. He explains to the confused toddler of the various anatomical parts of his offspring as seen on the ultrasound screen much to the annoyance of the attending obstetrician. The doctor who is still living suspended in the good old time where children were seen and not heard,  seriously wonders whether the child really understands what in heaven's name is going on, but the father's duty has to go on! He is waiting for the son to ask the father, "Who put little Tommy in?" just like he heard his mother read to him the nursery rhymes "Ding Dong Bell".
In his own mind, the obstetrician shudders what the father would say to son when he is literally caught with his pants down during his nocturnal orchestrated manoeuvres in the dark?
I thought children were to explore things themselves, learn the hard knocks lessons of life through self discovery and research rather than being spoon fed information that they sponge up as they pompously slide through life mollycoddled and sugarcoated....
