Twin-sleep

The girls are excellent sleepers and have been sleeping through the night (8pm-8am) for a few months now. They had been doing two daytime naps until last week, when they transitioned to a single 1-2hour nap around noon. They are still sharing a crib and even though we always start them on their own end of the crib, during the night (or nap), they squirm around until they are touching. They've ended up in some pretty hilarious poses but don't seem to bother each other. We put them in sleep sacks at night (bottom pic), but they don't let the sacks get in the way of interlocking twin-twin interactions.
