Eastenders actor, Rob Kazinsky, has revealed how hard he found it whilst filming an upcoming storyline for the soap.

Rob plays Sean Slater on the show and soon he and on screen wife, Roxy Mitchell, face their biggest challenge yet when their baby is born prematurely and fighting for its life.

As part of their research, Rob and Rita (Roxy) visited a neonatal unit at Barnet hospital, north London.

Speaking to the Daily Star, Rob said: “We got shown round the wards.

“Nurses spoke to us about what we would be going through if we were really having a premature baby. I was left completely heartbroken looking at the tiny babies, some of which were no bigger than my hand.

“I feel so sorry for the parents who have to go through it for real.”
