Baby Coughing In Sleep

When does a baby cough become serious?
My 8 month old has never had a cough till today. She’s in bed sleeping right now and she’s getting coughing spurts, is there anything I could do to help her? I do have a cool mist humidifier in her room right now.
And what symptoms should I look for before actually needing to get it checked out?
Please no rude comments, its night time and her doctors office is obviously closed or I would have called there. Need mommy opinions that have went through this. Thanks
The humidifier is great and get baby balsam or vix to rub on her chest I wouldnt worry untill she gets flemy or it starts sounding bad. Its only normal for you to worry your a mum! Good luck
