Young babies are so simple and full of innocence — or are they?

Mom of three and YouTube vlogger ItsJudyTime [1] just proved that even the smallest of littles can be sneaky and cunning. She put down her twin girls, Keira and Miya, for a nap, and was watching the baby monitor when she saw them standing up and giggling away with each other in their pushed-together cribs.

Watch what the girls do as soon as their mama calls to them over the monitor — it's priceless!
