I give my LO warm baths, and I use a vaporizer in her room for a couple of hours (the kind that have eucalyptus smell) it seems to work better than the humidifier.
Lo is just getting over a cold. We used a humidifier (doctor recommended a cool mist one), saline with bulb sucker, sleeping on an incline (HUGE help), and showers with mommy. There is also a Johnson and Johnson vapor bath that is safe for 3 months and up. It smells like Vicks, but doctor said no to that. Thought this bath wash would be the next best thing.
Re: How to deal with congestion?
Bring him in the bathroom with you while you shower, or shower with him if he likes it!
Yep...run the hot water and let the bathroom get nice and steamy. It should help to break up some of the congestion.
