Is it okay to let my daughter call my boyfriend daddy?

Abby • Mom👩‍👧 RN 💊 Wife 💍

My daughter is about 20 months old. Her biological father took off when I was pregnant and I've never heard from him since. He's never tried asking about her, seeing her or anything. I started dating my boyfriend about a year ago. (When my daughter was about 9 months old).

My boyfriend has completely taken her in and treats her the same as his own kids. We're going to be moving in together in a few months. I always address him as his first name to her, but recently she has started calling daddy.

Should I try to continue to correct this or not?

We want to get married when I finish nursing school and he wants to legally adopt her when we get married. She's the only dad she's ever known or ever will. I'm not sure what to do.
