Ex-EastEnder Natalie Cassidy has criticised the soap for paying "poor attention to detail" in the controversial baby swap storyline.
The Walford show has drawn thousands of complaints from viewers of the plot, which saw Ronnie Branning swap her dead newborn for Kat Moon's healthy son.
Natalie, who gave birth to daughter Eliza in September, told New! magazine: "The cot death storyline in EastEnders has stirred up a lot of emotion.
"I think the attention to detail was poor - Ronnie walking around hours after giving birth.
"Also, mums are advised to keep babies in a Moses basket until they're six months and you wouldn't leave a newborn on the bed like Ronnie did. That said the acting has been sensational."
Samantha Womack, who plays Ronnie, is bowing out of the soap this year, but her agent denies that her decision was motivated by the contentious storyline.
Natalie said: "I know how it feels to have big story lines take up your time and energy, so maybe it's her time. I'm sure she'll continue to have a great career. I wish her lots of luck."
