Can broncilitis clear up and then come back??

[999HELPMYPUDDINGSONFIRE]

My little girl had it 4 weeks ago and was in hospital for
3 days for oxygen suuport.
For the past week and a half she's been fine, no coughing etc.
However since Wednesday she has started coughing again and it's steadily getting more frequent.
She had her first injections Friday so I'm not sure if this could have worsened ye condition?
I know the cough can linger but I find it strange that it went completely only to return nearly 2 weeks later.
She hasn't had any coughing fits which led us to hospital the last time thank god but I'm still so worried.
She's only 9 weeks old :-(

Yes it can, what you need to watch out for is if her breathing is in distress.

If you can see the notch at the top of her chest when she breathes in, if her ribs cut into her tummy when she breathes in, if her nostrils flare she's having trouble and you need to get her seen again.

Hope she's better soon, ds had bronchiolitis at a week old and it was horrid :(

Yes it can, but it may not be related to the same virus especially if she just had her first injections. You need to watch for these signs as if it worsens she may need to be re-admitted. Do not wait or worry about taking her in if you are at all concerned, that is what they are there for or take her to GP on emergency appointment today if you can get one or in the morning to double-check.

Fast breathing, difficulty with breathing, and wheezing may develop as the infection 'travels' down to the bronchioles. The number of breaths per minute may go as high as 60-80.

The nostrils may 'flare' and the cough becomes worse.

You can often see the muscles between the ribs moving inwards during each breath. This is because the baby needs more effort to breathe than normal.

The baby may have difficulty feeding and taking drinks. This is because the baby is ill, tires easily, and may struggle to breathe and feed at the same time.

Thanks.
When he had it before within 2 days of the cough she was having coughing fits, would go bright red and struggled to get her breath.
This time it's just a cough, there's no fits per se and it hasn't got any worse
