Isabelle hanna- pretty! I prefer the spelling isobel though. Spelled isabelle it seems to sort of hide behind all the frilliness. Hanna looks more complete as a mn spelled hannah.
Abigail karen- I love the name abigail. It is so sweet that your considering karen after your friend. Other forms of karen that I love are kerensa and karina.
Dakota belle- dakota is a boys name to me. Belle is nice as a mn. How about danica belle?
Chandler christopher- too much alliteration to me. Chandler is very trendy. I love christopher though. How about sean christopher?
Braedon alexander- I prefer the spelling braden. You should be aware, though, that the -aden names are getting very popular. I love brendon more than braden. Alexander is a handsome classic.
Bailey abbott- nice! I love seeing bailey as a boys name. Abbott is a strong name that compliments bailey perfectly.
