Congrats! :)
I remember that you liked
Jonas for a boy (as your SO's fn is
Jason, right?, and it's an anagram). So if you want to go the J-route and you do have at least one boy, I think
Jonas is a good idea. Otherwise, I'm not a big fan (personally) of siblings all having the same first initial. :-/
