This is what my friend did. When her baby was borned, she only picked up her baby to feed, change, bathe and the occassional rocking and cuddling. But she made sure that the baby never got the chance to fall asleep in her arms. She did this for 6 weeks. By then, the baby was already able to self-soothe. He could lay awake for an hour at times, starring at the mobile in his crib, before falling asleep. I was worried that her baby was going to turn out into a quiet, withdrawn one, but now at almost 10mo, he's a happy, well adjusted baby whom was slow at meeting his milestones initially, but is now ahead in many. It's a form of training - with no crying involved.
