Colin home sick

Colin is home sick today. He had a rough night. He was congested, sneezing & coughing most of the night. He didn't get better until after 4 a.m.
It's a tough allergy season this year. He doesn't have a fever but he got sick at school.
I just called to check on him, he was coughing every other word & breathing hard. He sd nana was in the garden. Now, when I call there is no answer.
G just finished up his Dr appt & is on his way to pick him up.
