The older weasels started sharing a room two nights ago. Serena has her own bed, but prefers to sleep with Bri, which is what I expected to happen.

Night one went about as well as could be expected, they stayed up really late. There was a lot less fighting than anticipated however. Bri conked out at about 11, and Serena held in until 12. Bri taught Serena how to turn the lamp on and off, so mostly Serena just flicks it on and off all night.

Night two was better, Bri was out at 10 and Serena 11. Serena even turned out the light last night. My goal is to get them both sleeping by 9 most nights.
