How do I get my cockatiels to stop breeding?

I have two cockatiels that just won't stop having babies. They first started having babies around easter of 2005 and have been non-stop since. As soon as the babies are old enough to walk out of the breeding cage they start doing it again. Sometimes as often as three times a day.

We've tried removing the breeding cage and nesting box but they'll lay eggs next to the couch and try to hatch them there. I'm worried about the health of the mother since I've heard they may pull calcium from their bones to form eggs. She eats lots of cheese and chew the calcium block plenty though.

I can't and won't separate the pair since they are in love and will cry and scream if they can't be together. Does anyone have suggestions on how to stop them?

I also have two parakeets, one lovebird, and another cockatiel. Thank god they are all males and can't breed with each other.
