Oh no. My heart is so sad for you. Hospital overnights are hard. Try to get a break soon. Go get some fresh fruit and a coffee. Deep breaths, check in with people, walk a few laps. You are surrounded by people who are going to take care of Lincoln. Don't forget to take a little time for you today too.
Can you ask about discharge? I would ask what "the plan" is as far as testing, care and discharge.
How is Lincoln feeling today?
