I have for one each of my 3 children. They have had them since birth and are are definitely comforted by them. I think at about 5-6 months was when I really noticed they wanted their comforters and it soothed them if they were upset etc. downfall is obviously they can get too attached and if u loose one when you're out it's hell to pay. My kids have 4 each - 2 in rotation as they get feral and 2 stored away in case of an emergency. I plan to always keep one never opened and give it to them when they're older for their child one day.
