Might be normal
Well, I have to say that i hear this in the office every day.
Parents say 'my child has been sick since halloween', etc. Problem is, that mostly this is not one long infection, but rather recurrent colds. Especially if the child has older sibs or is in day care
, the average kid will have 1-2 colds per month and therefore seems sick all the time. Life is like a rollercoaster -sick, better, sick...
