Any tips for helping congestion stay away at night for a toddler?

Keeping my niece for a week, she’s 2.5 and she’s been sick w a cough/nasal congestion but it’s really gone away and it’s only bad in the middle of the night/morning her nose gets super stuffy/dry & the humidifier doesn’t seem so be doing any good😕 poor thing always wakes up not feeling so hot
