4getmenot, I see why they have done it, but soaps work because people relate to stories,charathers and events. Eastenders are quick to add media story lines into thier plot (remember the odd underground episode with Billy - and tube bombings) that clould have been seens as insensitive too.
Your right I don't think Maddies parents would mind or even be watching. With Eastenders loosing ratings so drastically at the moment they can't risk loosing any more viewers, plus being in the media now stating they will change the dawn baby plot, may be a blessing in disguise and actually encourage people to watch it.
