My 6 month old is waking up at night with a nose so blocked she can't breathe out of it at all. Considering she normally only wakes up once a night but last night was every 2 hours, I wondering what I can do. Have tried Karvol, mattress raised, saline drops, Medised...! But last night was a killer - I nearly left the house this morning without shoes on thanks to extreme tiredness. Weirdly she doesn't seem coldy during the day-no runny nose etc..
