In December 2010, Ronnie Branning (Samantha Womack) swapped her newborn baby, who died in cot, with Kat Moon's (Jessie Wallace) living baby. Around 3,400 complaints were received, with viewers branding the storyline "insensitive", "irresponsible" and "desperate". Roz Laws from the "Sunday Mercury" called the plot "shocking and ridiculous" and asked "are we really supposed to believe that Kat won't recognise that the baby looks different?" The Foundation for the Study of Infant Deaths (FSID) praised the storyline, and its director Joyce Epstein explained, "We are very grateful to "EastEnders" for their accurate depiction of the devastating effect that the sudden death of an infant can have on a family. We hope that this story will help raise the public's awareness of cot death, which claims 300 babies' lives each year." By 7 January, that storyline had generated the most complaints in show history: the BBC received about 8,500 complaints, and media regulator Ofcom received 374. Despite the controversy however, "EastEnders" pulled in rating highs of 9–10 million throughout the duration of the storyline.
