Sick 6 month old

Just want to see if anyone can relate and share some helpful tips on sick baby.

My baby is 6 months and a half and is going on a full week of runny nose and little cough (due to the runny nose) she has no fever but the runny nose won’t let her nap and sometimes gets bad that she throws up after her bottle due to the boogers. I suction her and have a humidifier but nothing seems to help slow it down. I haven’t tooken her to the doctor because they always say the same thing and she’s eating good and giving me wet diapers .

Any comments appreciated 😊
