Pronounce as Meeko or similar to Mico. This has been my nickname since birth, made from my Aunt. It is short for Michael & I guess people just like it haha. Especially that it’s named after the racoon from Pocahontas girls just think it’s pretty cute 😉 I personally like it because it seems unique to have a name similar to Miko spelt with a “C” instead of a “k”.
