yeah ok, parents arguing in front of children is perhaps ok to a point. But at what age?
I dont see the point of preparing a child for a breakup unless its possibly on the cards, otherwse its surely going to upset the child, especially when young. Yes, by all means explain things if and when they come into contact with such situations, ie if friend Billys parents split explain that some families do change.
But i dont see a point in explaining to a 3 year old that parents sometimes split if they dont need to know that. Otherwise every argument between parents could terrify a child thinking that they may split.
