I wore a tshirt all day and night and the just wore it to bed a couple of nites before we got our bailey, then when we braught him home I held him alot that day and he got the smell. then when we put him in the crate for bed I put the tshirt in with him for the first week and faced t he crate towards my side of the bed where he could see me. He goes right to sleep and we never hear a peep out of him till we take him out in t he morning. We have had him about a month now.
