Armed with his phone, the dad went to investigate.
To his amazement, he found them playing peekaboo with each other from across the room.
“They go to bed at 7.30pm and they're supposed to be asleep by 8pm but somebody forgot to turn the light off,” he said.
“It was the first time I'd seen them playing peekaboo which is more why I filmed it than anything else.”
The one-year-old girls might be identical, but their dad says they are completely different inside.
"They're supposed to be identical but their personalities are so different – Molly is very much the boss and Megan is the dizzy princess," said their proud dad.
"Megan won't feed herself, she insists on being fed like a princess would whereas Molly will grab the bowl out of your hand and throw it to the floor."
