Sometimes it's hard to know if your child is really coming down with something or just suffering a bout of Mondayitis.
For safety's sake, if your child seems unwell you should always keep them home from school and seek medical advice.
However, if they miraculously recover by 11:00am, ready to race around the backyard, keeping them in bed all day may send the message that staying home isn't nearly as much fun as going to school.
