Sleep Training Experiences?

Have any May '16 mommas sleep trained their babies? Mine is waking up every 1-2 hours, and I can't function, but I hate the thought of Cry It Out. 😔 Also, he used to sleep through the night till he caught bronchiolitis about 5 weeks ago. I'm not convinced he's totally over it (still occasionally gets a wet cough, especially after we do breathing treatments (they have to happen right before bed) and will end up in a coughing fit when I do let him cry a bit at bedtime). Also, about a week ago, he was up frequently at might like this and it turned out he was cold so if we had cried it out at that time, I would have felt awful. I'm just afraid if I do CIO, he'll *actually* need something physically (beyond comfort) and I won't answer, which is awful in my mind. Any advice or experiences you ladies can share??
