Congratulations on your new son!
I shall assist you the best I can :)
Life hack: name your kids something starting with the letter 'A' to have them first in line for anything that is sorted alphabetically.
My suggestion then is: Abel, since you like 4 letter names and it starts with 'AB'.
Aside from that, I think Hawk is a cool name ^_^
Interesting Advice. First in the Alphabet :) Abel is cool and hawk is great!
