My one month old is very badly congested at night. At about 1-2 weeks old she got a cold and has been sneezing out green snot. Now that's stopped but she can hardly breath at night only. I've tried fess little noses, raising mattress and a vaporiser. Nothing seems to work. It starts around 1.30am and the congestion is so bad it keeps waking her up and she sounds very distressed. It goes immediately if I pick her up and hold her upright, but I can't do that all night long. Even if I cradle her in my arms (nearly flat) it goes, but as soon as I lie her down she can't breathe properly. This is the same place she sleeps during the day with no problems. Pedi is on holidays, the GP just says oh she looks perfectly healthy. Anyone experience this or know what's happening?
