DS has been a bit poorly with his chest we kept him off on Friday and he's had to have his blue inhaler a couple of times he's 5. He's okay now apart from a cough and a bit of a snotty nose. He's supposed to be having his flu nasal spray tomorrow but DH thinks we should pull him out and get it done at doctors instead? I'm worried it could affect his chest negatively, are we being over cautious?
