I'm a FTM and my 3 week old baby has a cold and I dont know what to do

It gets me so upsetting to see him like this. He coughs a bit and sounds very congested. He sneezes but nothing comes out. I hate seeing him like this because he doesnt sleep well. I have a visit to the doctor next week but I'm not sure if I should go by tomorrow. I would really like some advice from moms out there!! Any home remedies or recommendations? I've tried saline drops but it only helps a bit

I have a humidifier also but I guess time will tell if its helping the baby. PLEASE HELP!
thank you!!!
Re: Baby has a cold, please HELP!
Some essential oils (diluted) are safe in infants as chest rubs to help break up congestion. But please do your research on which ones.
It's very stressful to watch your infant be sick. Especially as a first time mom. I'm sorry!
