Same thing here too!
This is round 2 of the "cold" this month which for some has resulted in croup, ear and chest infections.
I am also 18 weeks pregnant.
I have changed my sick policy now. I realize colds are common and go around. However, if its a Monday morning or the child has been away I am now asking parents to check with me first before sending their child with cold symptoms. If there is a cold going around already here, they may send them as long as the child can participate, if no one else is sick here please keep them home.
