Does anyone else have a baby who is NOT sick but sometimes sounds sniffly and congested? If so, does it seem to be worse at certain times of the day, like night and early morning? Anything you do for them or do you think it is just "normal"? DS often sounds fine and then other times he seems really congested, but there isn't any mucous there. It just "sounds" like it. He's pretty happy otherwise! But he's not the world's best sleeper and I'm wondering if this is waking him up. I'm still just trying to figure out if anything is wrong . . . Thanks!
