Stella called this morning and said that Marek's values were good enough that they were letting him come home today!
They had turned off the cortisone last night, which apparently meant that the child was as good as discharged already, and this morning, they said he could go home. So Stella called me and asked me to come with Marek's car seat.
So now all of us are safe at home. And Marek is really quiet; he seems to be happy just lying there in his bouncer without being carried around or fussed with—just as long as nobody's jabbing things up his nose or in his foot!
