The show's dramatic New Year plot will revolve around Ronnie Branning and Kat Moon giving birth, only for Ronnie's baby to tragically die when he is just a day old - driving her to swap her son with Kat's baby.
EastEnders' executive producer Bryan Kirkwood told PA: "We're very aware of the need to deal with such an emotive subject matter as sudden infant death syndrome sensitively in what is a very powerful, dramatic storyline."
One scene which has been specifically subject to "small edits" is a shot of Ronnie, played by Samantha Womack, touching the hand of her dead son.
The audio has also been altered when the distraught mother, who is holding the lifeless body of her baby, hears the sound of Kat's infant crying as she stands in the square.
Further changes have been made to a scene where Kat (Jessie Wallace) is discovered in bed by husband Alfie (Shane Richie) after having haemorrhaged.
Kirkwood commented of the moves: "These are small edits which we have made being mindful of viewer sensitivity but which will in no way detract from the compelling drama, dialogue or performances."
A source at the show added: "We didn't want one scene to overshadow a really powerful story."
