Thanks everyone. Df's taken him down to the medical centre again now... They'll send him on to hospy if needed. They are generally pretty good if you explain it was here or hospy will see him next rather than waiting.
Thanks again. We have had many issues with this with ds1. We both have asthma so chances are... I think df was a lil apprehensive because ds2 has been admitted to hospy in the last two weeks (unrelated)... When it rains it pours!
