Help!! Sinus troubles with baby!

Kaley

My daughter is almost 9 weeks old.

She is having a lot of sinus drainage. I have the NoseFrida and I have been using it all day. But I only get little bits of clear mucus. No green or yellow or anything. The problem comes with the fact that any time she is laying down she coughs and gags because of the drainage. She cant sleep or even get a diaper change without gagging and coughing.

What do I do...

I am freaking out here
