How fantastic you are chosing to not know the sex of bub (i think that's what you mean, LOL)... we did the same and it was the most wonderful gift we could have ever given ourselves, after all the work in birth and baby arrives it's just amazing but to top it off with the surprise of now knowing the sex of baby is like one moment you have won 1st division in the lottery and the next moment you have won 2nd division on top of that ... nothing bets the feeling ... DP & i will never ever forget that thrilling feeling of finally knowing the sex of the baby, i could never out that feeling into words, it was priceless & the excitement was beautifully given to everyone else that day of our DD's birth

I just love your boy's names Hudson, Lucas, Aiden & Zane Especially Aiden that was on my boy's list. Also we had Kyran & Kynan if you would like to choose from those

As for your girl's names i like your choice of Bianca, Ebony & Eliza ... (My SIL is a Casey)
