EASTENDERS fans spotted a blunder during tonight’s live episode as Sonia’s baby grew dramatically in size between scenes.

During an incredibly harrowing episode Sonia – played by Natalie Cassidy – was seen giving birth in the Queen Vic, with Bianca Jackson and Lauren by her side.

But as her little girl arrived she failed to make a sound, leaving viewers fearing she had passed away.

The baby began to turn blue and Sonia was seen struggling in the aftermath before the baby began to cry as emergency services arrived to rescue them.

Eagle-eyed fans couldn’t help but notice how the child was initially very small before she appeared much larger at the end of the episode.

Discussing the moment, one person wrote: “Why has Sonia’s baby aged 10 months in 15 seconds.”

A second added: “Sonia’s baby has tripled in size within 5 mins…”

While a third remarked: “Size of that baby.”

Another commented:. “Sonia’s baby aged 2 months in 3 minutes.”

Sonia also revealed she had chosen to name her little one Julia.

Sitting in the back of an ambulance, Sonia told her baby: “So welcome to the world Julia, it’s all about to begin.”

Viewers also had the choice to name the baby Toni, paying homage to EastEnders’ creators Julia Smith and Tony Holland.

Elsewhere in the live episode Martin Fowler, played by James Bye, died.

His death came as a large metal beam, which fell on him in the explosion at the Queen Vic pub on Wednesday’s episode, was lifted off him by the emergency services.

Stacey Slater (Lacey Turner), whom Martin had just successfully proposed to, had kissed him before the beam was lifted, telling him “it’s going to be alright”.

Martin appeared to be safe but moments later went into cardiac arrest, with paramedics unable to save him, having earlier warned Stacey her fiance may have crushed syndrome, causing kidney failure and heart failure.

Martin’s father Arthur, played by Bill Treacher, appeared in the first scene of the first EastEnders episode in February 1985 – and he was the first baby born on the soap.
