humidifier & 3mo.

My son will be 4months old on the 10th. I couldn't completely understand the pharmacist when he was explaining to me(my 10yo stepson was blabbing away about other stuff)  all i heard was the hot humidifiers could make him stop breathing. I bought the starry night cool mist one. He has a congested cough, and a stuffy nose. He's formula fed.
