8-month-old Delilah has her first cold and keeps coughing all night

I feel so bad for Delilah 😞 8 months and has her first fold, finally at the end of it but she keeps coughing, went through all the kids and finally hit her. Of course it’s viral so nothing to give her except Tylenol. Wish I could take it away! Poor girl keeps coughing all night and is still awake. On the bright side I just checked her mouth and she officially has her first 2 teeth broken through the gums finally! Just wish I could help her cough ugh. She’s so cranky and refuses to sleep 😞 I’ve done all I can to try to clear her out, warm mist, nose drops, nose sucker, propping her up ugh nothing seems to help.
