How can I help my 15 month old that has a cold? 😢

My poor 15 month old (almost 16) has a cold. He nose is all stuffed up and he keeps coughing. I feel so bad for him.

What do you suggest I do to help him (especially at night) so that I can get some sleep as well.

I have been using the saline mist and clearing his nose but he hates it so he’s crying which creates more snot 🤦🏻‍♀️ I also rubbed baby Vick’s on him last night. Any other suggestions?
