There are pro who don't need a training or certificate to be a pro,because they're friendly, wise,confident,literated, accepting any race,cultures and religions., and know basic knowledge about mental health especially excellent customer service, without good customer service anything can go wrong like violence. But in my opinion to be a pro should have certificate as a cuddle therapy ,basic knowledge about mental health,cultures,religions because they're are people who need cuddle some for emotional reasons,some have mental problems also for precaution reasons for both parties so nothing can go wrong.Like a security guard have license and basic knowledge about health and safety to protect people from any harm .I have nothing against pros all my pros are amazing wise,literated and have a good customer service. What's your opinion you can disagree if you like,but you don't like the topic don't comment.
