Baby names and the daddy's family

Brandi
This is my first post on here lol we have two beautiful names picked out. Aiden Alexander for a boy and Skylar Nichole for a girl and my husband's sister keeps trying to get us to change the names because 1. Aiden sounds like her son's name (Brayden) and 2. She just doesn't like the name Skylar. His family really loves me and I don't wanna ruin it by speaking my mind about her trying to change the baby's name. Just getting really irritated 😡😡😡😡
