need sleep help

Did any of you not let your LO CIO?

DS has been a great sleeper since we brought him home from the hospital.  For the last 3 or 4 weeks however, he is waking up every 3 hours or so.  Our regular routine of rocking and sleep sounds lulls him back to sleep (or sleepy) but when we put him down, he jumps up and cries (screams, really).  We made the mistake of letting him sleep with us - because we  had to get up in the morning and now he's hooked.  I'm not sure how I feel about letting him CIO but I feel like letting him sleep with us is not okay either.

Any non-crying sleep solutions work for you?  Please share.

TIA
