I am so glad that it did not happen to me and never can. What would parents do if they did not know the kids were swapped if they were older like in Corrie (who did not resolve it but the children are still with the "wrong" parents. So why did no court made a decision there? Because the kids are older?)
Very well acted from all characters in my opinion and my heart goes out to all of them, what a situation to be in.
