Quoting PoopyPolice:" My son has been congested going on 4 days now. My SO's mom got him a Vaporizer? I think that's what they're ... [snip!] ... tips. I hate to see him like this. I can't sleep because I'm up half the night checking up on him (my poor lil man ) "
When my son was congested just before he turned 4 months old, he had a hard time breathing so I had to suction out his nose every hour or so. Well, his doctor suggested using Saline spray for his nose, which is the kind that is safe for infants. I used that on him every hour, gave him a warm (with slight steam rising) vapor bath and since he slept in our room in his bassinet, I raised the upper part of his mattress so his head was elevated so he wouldn't cough as much so he was able to breathe better. I even took him into our bathroom after running VERY hot water so the room would be very steamy and help his head as well.
It helped him to get over it a little quicker because of everything I did for him, it lasted for about 3-5 days, plus he was and still is teething as well.
