My two week old had been extremely congested since we came home. I have been vacuuming every day since we have dogs and I dusted the place top to bottom. We also have a humidifier and use saline drops constantly. She sleeps with her mouth open and can hear her wheezing. Obviously google gives me a ton of different answers and when I told her pediatrician she just told me to keep using the saline drops and sucker. If anyone has any other suggestions let me know!
