I had the same problem with my son when he was little. He refused to sleep in his crib at all!! Finally, we ended up putting him to bed, and we had to let him cry for 10-15 min at a time. We would then go in and comfort him, without picking him up. Once he was calmed down, I would leave the room, and continue to come back every 10-15 mins until he finally fell asleep. It took about a week or two but finally he started to sleep in his crib. I hope this helps...Good Luck!
