I actually find boys names more easy to decide as there are too many girl names to choose from. I also am pretty set on my chosen names, but I just love names and everything too.
Zack - Not a fan
Aaron - It's okay.
Blake - LOVE!!
Alexander - Love this, esp for a MN. Blake Alexander sounds pretty sharp
Callum - Not a fan
