Hello ladies! Could you please advise, has anyone encountered such a situation? The baby is 20 days old and he has mucus in his nose, I don't know how to suck it out. I rinse with Aquaviol and aspirator, I suck it out with a syringe, it won't hurt, only a little comes out, can't suck normally, spits up through both nose and mouth, and the nose itself is clean, constantly wiping with tweezers.
