Twin Name opinions

Megan
Hi everyone! I'm currently 25 weeks pregnant with Twins, a boy and a girl 😬 we are so excited! We already have a 3 year old son, who can't wait to be a big brother! But I'm having a dilemma wth choosing names. I love the names Aiden and Alessa..but my sisters names is Melissa. My mom seems to think Alessa is too close to Melissa's name. I will probably call her Allie for short. Any opinions?
