name opinion

We have a son named Matthew, and my husband is named matt too. We're having a girl and I've always loved the name Madeline/Madelyn but I'm worried it's all too similar. I call my son Matthew but anticipate I'd call my daughter Maddie at some point. Are the names too similar? Am I going to lose my mind trying to figure out who to yell at when we're both toddlers? Help!
