Morning of my first day of school

Mason just threw up all over the sofa so I guess that answers my question as to if he is still feeling sick. He looks pale and dehydrated. He hasn't eaten since Saturday. I have no choice but to send him to daycare. I can't miss my first class at 8am! What a great way to start off my school year! Do I tell the daycare people or not? Dilemma.....
