How about this spelling?

I like Dayne because it does keep the "y" as with your other children. My hubby and I couldn't agree on a name either it took us forever. We are having a boy and this is our last child due to my blood pressure issues my doctor doesn't think it would be smart to have any more, but we have a girl and a our boy due in August. But anyways back to what I was saying... lol.. pregnancy brain kicking in... He wanted to name the baby after his dad and his name is Danny (not daniel) so we had to find a name to flow with it which is virtually impossible so we are using danny as a middle name and naming our baby Jaxon which nobody on his side of the family likes, but its one name we could agree on so we are going with it so we don't have a no name baby :-) I think Dayne is a wonderful name. Good luck
