She's 2.10 and she had a bad phlegmy cough over Christmas but that's gone now...she does not seem at all congested in the daytime...no runny nose.
At night since the cough and cold she has been breathing in really loudly...it sounds like her nose is stopped up or something...like it's an effort to get the breath in...then every few breaths it sounds as though breathing out takes a moment and the breath kind of "pops" out...like a cork has been removed....what is this? Is it to do with the cold she had?
Her room is clean and dust free...she's not had problems before...
