Andy Keher was just checking in on his twins Molly and Megan, who were supposed to be asleep.
"I put the babies to bed and after about half an hour I went back and could hear the sound of giggling from the corridor," Keher told the Liverpool Echo. "I crept in and videoed them playing peekaboo with each other which is something I’d never seen before."
Bless. And can you blame them? Chatting and playing peekaboo is far more exciting than sleeping... especially when you've got a twin to do them with!
