Kelly managed to continue the interview.
After the interruption this morning Kelly apologised to Dickens.
"We've just heard your child having a good old yell in the background," Dickens said.
"Sorry," Kelly replied quickly.
"It sounds like you've got up, walked into the hallway and sorted him out," Dickens laughed.
Kelly apologised again and the pair continued the interview.
The interview came two days after South Korea conducted its first live-fire drill for an advanced air-launched cruise missile that would strengthen its pre-emptive strike capability against North Korea in the event of crisis.
South Korea's military said the Taurus missile fired from an F-15 fighter jet travelled through obstacles at low altitudes before hitting a target off the country's western coast during drills.
