Update from 3:30 AM phone call: Max's head circ up +0.5 cm to 35.5 cm.
We really shouldn't stay up for the nightly head circumference measurement (usually around 11:00 PM), but our loss of sleep is your gain. When I called tonight, however, Nurse S. told me that they're going to weigh Max, measure his head circumference, change his diaper etc all at once, and not for another half or so. This is known as "clustering of cares" and of course it's a great thing. However, she assured me that Max was "pooping up a storm and sleeping like an angel". Earlier, she had reported that Max was enthusiastically sucking on a pacifier. That's enough for tonight. The head circumference will have to wait until the 3:30 AM phone call.
