Kidergartener sick every week!

My son is 5 and started school this year. It seems like every week he’s sick with something. As soon as he starts to get over it, he gets sick all over again. Today he was coughing and this afternoon he has a high fever.

Im getting frustrated and my son is too.

Is this a normal thing? He was never in daycare or preschool or anything like that.

It’s adding to my long list of reasons why I don’t like this public school he goes to.
