I was wondering the same thing not to long ago! DS has had a cold for a few weeks no temp, it went away but now its back with a nice bark to it and green snot, hes not getting any better and i think this time he needs a bit of help So off to the docs we go, generally though i would wait it out and we had been but it seems to be alot worse this time.... still no temp though hmmm

Fingers crossed your little man is well again soon oxo
