Mia has a cold and she's all stuffed up. She wakes up at night because she can't breathe. It's hard for her to eat because she can't breathe through her nose. I try to suck it out of her with the nasal aspirator, but her it's hard to clear her out. We have a humidifier in her room which we thought would help, but it doesn't. I have some saline drops is it safe to use them to help loosen things up so it's easier to suck out her nose? She's not quite 3 1/2 months old, is there anything you can suggest that will help my poor little baby breathe?
