DF has had the flu for a fortnight now and is only just starting to look like he's getting better. Heachache, snotty, sore throat, aching and coughing his lungs up.

The last few days DS has been a little snuffly and a tiny cough but today he is really blocked up and the cough seems to be getting worse and he's swallowing constantly like he has a sore throat.

He seems happy enough and he is still feeding so far and I don't "think" he has a temp but our $80 thermometor seems to be out because I am pretty sure I have a temp of more than 35 degrees.

At what point should I worry or take him to the doc???
