do you believe in spiritual mediums ?

Santina • Mother of 4 and soon to be 5 due February 2020 and super excited. Married to the love of my life! Life is pure bliss💕
My husband lost his younger brother in 2011, and his sister when he was a teen and his father when he was 10 I believe. He always talks about them and how much he misses them and about the memories. I would love to get him an hour with a medium for a gift. He strongly believes in them and I think this would be an amazing  experience for him. I'm very skeptical of mediums but I don't not believe I'm just unsure. What are your thoughts. And if you've ever had a reading done what are some things I should look for when looking for someone. 
. Not really sure where to post so I bought controversy would be best 
Thanks so much for taking he time to read and respond
