I put mine in the dryer. Everyone has there own preference but I'd just watch what kind of dryer sheets your using. I don't use any except the soap and sheets that are made for babies.(it didn't have to be) Baby skin is very sensitive and you don't want her/his skin to get a rash.
I just put mine thought the dryer... It doesn't matter
No as long as they are washed probably
It don't really matter does it?
