Coronation Street: Who's looking after the kids?

Just a couple of weeks ago we expressed concern about the welfare of the kids of (then) warring couple Dev and Sunita Alahan. They were rowing in the street, Sunita got arrested and Dev went drinking in the Rovers. No-one, it seems, was looking after their children.

Now it's Max's turn to go missing. Last night David and Kylie's marriage troubles worsened and Kylie packed a bag and left. She, David and Gail heatedly debated the situation for a while but at no point did anyone mention the couple's son.

'What about Max?' would surely be any responsible person's question? But the Platt's don't seem to remember that they have a small child secreted somewhere about the house.

I wonder how many of the writers or producers of the show are parents? A few of them must be. So why does no-one point out these plot holes sometime before the cameras roll? Leaving kids without supervision would cause a lot of fuss if the whole thing wasn't a made-up TV show - which (we must constantly remind ourselves) it is.
