Sucking his thumb

And holding onto his hair. Seems my children have a knack for holding onto their hair when they are sleepy. Vojta was already doing this when we were in the hospital. At least I have a very obvious, visual clue when they are tired! :-)
Magdalena is so happy that she can finally hug, kiss, and love on her brother since she's been sick for a week and we'd banned her kisses until she had "no more germs."
