Relactation

I’m a 49 year old women starting relactation so I can breastfeed my husband. I was wondering what supplements I should be taking and if anyone has succeeded at this?? I breastfed both my daughters and I was an over producer but that was 21 year ago. If anyone has any suggestions or has succeeded at this I like to know. My husband suckles at least 5 times a day and off and on throughout the night and I’m only getting little drops!! We have been at this for about a week. Just looking for some advice.
