I know, this drives me round the bend! I know that programmes would drag a bit if the main characters never got to finish a sentence, but it would be nice to see someone try and depict actual reality, just once, just as a sort of artistic experiment. There's a Norwegian author - Karl Ove Knausgaard - who tried to write about the reality of looking after small children in a book of his autobiography - my uncharitable thought on reading it was that it was only elevated to Art from whingeing by the fact that it was written by a bloke. If a woman had written such a warts and all view of day to day childrearing, the people queueing up to say she was exaggerating would have been falling over the people saying it was her choice to have a family so she should suck it up. But it is very well written.
On the TV the only thing I've seen recently that tried to be realistic was Last Tango In Halifax, where the son and his GF have a baby and from then on, that baby is in pretty much every scene where they appear. Having said that, 90% of the time the baby is in a carseat, and never seems to cry, so she's basically a prop. Still better than nothing though.
One that really drives me nuts is those housebuilding programmes, which I love, but which always airbrush out the kids. It's all "John and Michelle want this to be their forever home for their 1 year old Sophie and new baby on the way" and then they have two shots, one with the toddler in welly boots on site for like 15 seconds and then one of the newborn baby, and then you don't see them again, especially not at the end bit when they show them round the house. I like to picture the house with all the breakable things now crammed together on the highest shelves, and Duplo and soft toys scattered liberally all over every surface
