mixed up


I'm 22 weeks with identical twin boys, and several people have asked me how am I going to tell them apart when they are bored won't I mix them up. I have a good feeling I would just know who is who. But so many people have told me either paint a toenail or make them wear little bracelets. and it's bringing on major anxiety.WHAT IF....WHAT IF I get them mixed up. Let me know your opinions or your thoughts am I overthinking this.
