Need advice...

My 3-month-old is extremely congested and has a terrible cough. She's already been to the doctor, and the doctor said she's not sick. 🤔 The problem is, she's having a really difficult time eating because she can't seem to nurse and breathe at the same time. Any suggestions on how to get her to latch and eat well while still being able to breathe?

As far as the congestion goes, we are using saline to loosen the mucus, suctioning with both the bulb syringe and the nose Frida, laying her in an elevated position so the mucus can drain, and taking her into the restroom with us when we shower so the steam can help break up some of the mucus. If there's something else we could be doing that we are not, I'd love to hear suggestions.

Thanks.
