I personally like Bella Katherine, it sounds very pretty! For a boy I like Burke Andrew, Bennett is okay. Some suggestions are Bridget which can also be spelled Bridgit, Brigid, or Brigit, Brenda, Bethany, or Brianna. For a boy you could consider Brendan, or Bastian. Good Luck!

They are all pretty cute but my favorite would have to be for girl's names:
Berkley
Blair
And for boys:
Beckett
Bennett

I love all the names though. And on my daughter's soccer team (age 9) theres a girl named Brooklyn and I think thats very cute! But if you already have a daughter named BROOKE then that name might be to alike. And my other daughter's friend (age 11) is named Blakely. But that might be to alike Blake if that's your sons name. Haha sorry about those two names being very alike but maybe you'd like that.

Well let us know what you end up choosing and good luck with it all!

you have good strong choices, but there are a few things:
Blair may be associated with the blair witch project, but probably not with her generation. and i have a good friend named Beckett, he was called Bucket by his little sisters, and now at 26 he still cant shake the nickname.

another suggestion instead of Blair would be Briar, maybe Briar Rose like snow white.

Girls
Berkeley Kate (or Katherine)-not so much
Blair Elizabeth-love
Bella Katherine-not really
Brielle Faith- my fave

suggestions
Bella (nn Belle) Grace or Gracyn
Bridget


Boys
Brock Matthew-ok
Beckett (no middle yet)-ok
Burke Andrew-ok
Bennett (no middle yet)-my fave

Bennett Jameson

I wouldn't use Brock if you daughter is already Brooke - I'd personally find that way too confusing (but then I have enough trouble not confusing my son Balin and the dog 'Buck' lol)

B names I love (other than Balin ) are Bronte for a girl and Byron for a boy

Berkeley Kate (or Katherine) - Berkeley's a college to me, and a place, and a surname.. but as a name for a little girl, I really dislike it. Kate's gorgeous, as is Katherine

Blair Elizabeth - Blair's extremely masculine. Elizabeth's lovely

Bella Katherine - Bella's nice. I prefer it as a nickname, but it's nice as is as well IMO. This is my hands down favorite here

Brielle or Briella Faith - Brielle always reminds me of "braille" for some reason, and it seems like a nickname for Gabrielle (and Briella for Gabriella) instead of a full name. It just screams nickname to me, sorry :/ Faith's NMSAA

Brock Matthew - Brock's really unattractive IMO.. although Matthew's quite handsome

Beckett (no middle yet) - It always reminds me of bucket :/ or Beckham, as in David Beckham. It's nice enoguh, but it's NMS

Burke Andrew - It sounds like someone's name on attendance.. how it'd be last name then first name.. Andrew Burke sounds like a full name.. this just sounds off IMO. Burke's all surname for me. Andrew's wonderful

Bennett (no middle yet) - I prefer Benjamin by far, but this is nice. Benji Matthew might be cute
