My baby cries when he is put in his crib, How can i make him sleep in the crib?

I agree with Jamie. This takes a bit of try and error with the baby. For my son, it takes a couple of tries before I can fully put him down. It's easier to put him down after he's in deep sleep. It also helps a little if you can create white noise like "shushhh" while patting him after laying him down.
