How long does bronchitis last?

[sorrymissjacksonn]

DD is 4 months old really bad cough got much better now but it is still there worse at night. It's been a month now and it's still lingering.

Does it usually last this long?

Have you taken her to the GP? My GP always wants me to take DS in when his cough has been lingering for more than 7 days...

Coughs are always worse at night with young children as the mucus drips down the back of the throat making them cough. Unlike adults they can’t clear it without coughing. Have you tried elevating her head at night this would help her?
I’d take her back docs.. my DS was like this until about three ish, just viral coughs that lasted ages. Ever so often though it was a chest infection that needed a course of antibiotics to kick it

My DS had bronchiolitis about 4 weeks ago but still got the cough at night. I've done everything possible to help him but I might take him to the doctors to get checked out just in case.
