Lovey Introduction?

Are you guys introducing a lovey to your babies? I am considering introducing one. I'd have him snuggle with it during his bedtime routine now to start getting attached but not have in his crib until he turns 1. Hoping it would be a good comfort item to help him when he wakes during the night and maybe sleep better. But I also don't want him to get too attached in case it gets lost or forgotten when we go on a trip or something. Has anyone had experience with using a lovey?
