The storyline saw Ronnie Mitchell switch her dead son James for Kat and Alfie Moon's newborn child Tommy. McDermott - Ryan Malloy in the BBC soap - admitted last month that he would not be watching the drama unfold on New Year's Eve, due to his wife's pregnancy at the time.
"We didn't watch it because Michelle was a few days overdue when that was going on," Holy Soap quotes him as saying. "At the end of the day, if something is going to upset you don't watch it."
However, he added that he believed the reaction - which saw the soap receive a record number of complaints - had been "blown out of proportion a little bit".
"Janine tried to poison her husband at Christmas and stabbed herself and no-one blinked an eyelid," he said. "EastEnders does try and tackle these stories, like the paedophilia one with Whitney. They are difficult. Often when done well they hit the right nerve and people are affected by them. You get the complaints but people applaud it as well, and you don't hear about that."
McDermott and his wife welcomed their first child, a daughter named Arabella Betsy, earlier this month.
