My ds is almost 8 weeks old. For a few weeks now he's been pretty stuffed up, but it's off and on (he went a few days just recently where he was hardly congested at all). We got him some saline drops, which seem to help loosen the mucus, and it runs out most of the time. However, all night last night and all day today, he's been just terrible--you can hear him breathing across the room, the poor little thing

. And you are only supposed to give these saline drops up to 3 times a day. He's already had them twice today, and needs them again but I'll wait until bedtime, so he can breathe throughout the night...
Anyway, I guess my question is does anybody know what could be causing this congestion? I know it's relatively common for babies to have this--is it just because their passages are so small? I wonder why he's producing so much mucus...? My older ds never had problems with this...
Any ideas?

P.S. I did mention it to his doctor at his 6 week check up, and he just said that we'd keep an eye on it, and to just continue giving the saline drops to help him breathe (he also mentioned that he "hoped it isn't his adenoids"...?) He's not due to see the doctor until his 3 month well visit
