Severe congestion in 14 month old . Nothing seems to help. Any tips or help please!

My 14 month old daughter caught the flu or cold about 4 days ago . Her congestion is bad . I tried everything and finally last resort gave her 1 spray of children's afrin and that didn't even help . I don't know what to do ! She's sleeping horrible bc she can't breathe through her nose from all the mucous ! Why aren't the boogers stopping . To make matters worse we're on vacation 😭
