I see you are on team yellow... are you planning to use Kayden for a boy & a girl? Or do you have a diff name planned for a girl? Since this is a unisex name... Kayden looks like the girly version to me...
I think of Kayden/Kaiden/Kaedyn for a girl
and
Cayden/Caiden/Kaden/Caden for a boy
We had the name Caiden Anthony on our baby name list last time -- i think this sounds great together!
Additional suggestions:
Caiden Riley
Caiden Michael
Caiden Oliver
Caiden Alexander
Caiden James (love the initials CJ)
Caiden Joseph
