You can use sterimar saline spray and nosefrida aspirator to suck the mucus out. I went to my PD to help with the mucus suctioning as sometimes it’s too deep that it’s hard for me to manually suck it out myself.
Yes you can try using saline spray to spray baby's nose, then use aspirator to suck out the mucus 😁
