My now 14 week old baby is congested and has been now for weeks (7+). He's been checked by GP and his chest is clear but he's nasaly/sniffly/noisy breathing. I've tried the snot sucker, nasal drops ans spray and the snuffle baby vapour rub... Oh and the calpil vapour plug in bur he's still congested. Has anyone tried usinf humidifiers to ease congestion in babies, if so, did it help? Tia
