During my nightly visit to the sleeping trio I was surprised to find the "sissy's" sleeping in Gabby's crib, together. So peaceful- and cramped. I was tempted to move Mary back to her own crib (in order to prevent a meltodwn from happening at 230am) but opted against it... and they did, indeed, sleep through the night together. This morning, upon questioning as to why they were in the same crib, I was told - "so we could play together." Awwww.
