Well he slept 6.10pm-5.17am.
Presumably you'd expect a longer night if he was ready for no nap?
However, it was all in one stretch - the longest stretch of sleep he has had his whole life.
He protested that the sun was up but then accepted it and rested sort of til the sun came up. Up at 6.10 and I guess we go back to a nap day not having hot him any more sleep than normal
Oh, he got up and wanted to look outside to see if there was any sun outside too.
Yes room is as dark as it gets with tin foil over windows and curtains taped to the walls. Partner tells me B is not a lab rat
