cot training plz help

Currently goin through the NIGHTMARE of tryin to get our wee man (9.5months) to sleep in his cot in his room at night. We are on night 3 and are trying to do the cry it out method, were u put him down awake (after fed and bedtime routine)..he cries (screams) you wait it out 10 mins, go bk, hes stood in his cot, reassure him put him down, soothe for 1-2 mins then leave his room for another 10 mins and go through this process addin a few mins with the hope that he learns to soothe himself and goes to sleep. NO..after 2 night of goin through this for an hour each time to the point were hes loosing his voice crying so hard, weve only been able to soothe him to sleep ourselves in his cot, not actually him doing it himself..therefore when he wakes during the night he doesnt know how to get himself back to sleep therefore weve to go through the whole process again (usually 1am-2am) then he'l wake again at say 5am, and by that time wer absolutely shattered an end up liftin him to our bed, an then will wake for day at 7am.

i know this takes time but has anybody any ideas on how we could do this differently to maybe make it easier for everyone?

cheers
