<s>[INST] My 17 month old son has a shortness of breath and had a nose bleed incident don t know if they are connected and he s been having diareah and the sipping cough as we ll. is this a sign of a serious matter just today he developed the shortness of breath and the bleeding [/INST] Hi... I feel that he is going through a viral illness. But fast breathing s not a good sign to be left alone. I suggest you consult your physician or pediatrician regarding this. Bleeding can occur even due to trivial nose picking or due to viral illness per se. But as 17-month-old cannot pick the nose so effectively, I think it is related to viral illness and I suggest you see a physician or pediatrician. Regards -  </s>
