is there any way to stop crackles developing into a chest infection?

[chlochlo]

Ds is poorly again he's only just got over a serious chest infection.
Today he has been very grumpy and slightly warm and his chest sounds crackly and he's been quite out of breath.
Is there anything i can do to stop it before it starts (iyswim)

I'd give him a call if I was you.

Sorry not been on busy weekend. Sure this has been resolved one way or another and you don't need me to tell you this chlochlo but if he is needing nebulisers and steriods and not improving he needs A&E I know it's demoralizing, but it can get much worse quickly. I hope all is well. DS is couhging this morning and has just been sick I think i wont go today but see how he is tommorow.But as you said one doesn't want to wait too long .....oh dear
