I think try to find a name that sounds similar in both languages
We decided to slip cultural names between first and middle. He goes by his first name and with my family the second name from time to time
We call my child Indigo or Roux because we love both her names. And if she's being naughty it's Indigo Roux lol.
My daughters name is Valerie-Jean Estelle sometimes I call her Estelle
My son has 2 names but everyone calls him by his first name. I tried to call him by his middle name which I chose but he doesn't answer
