I have a few names that I found that I think can be very cute. (I do pick strange names I have been told.) Here is some that I picked out from the list.
Chocolate Baby (You can call them baby or Chocolate for short)
Sweet Cherry (Sweetie or Cherry)
Gypsy
Jupiter
Diamond
Tabasco (I think this would be a cute for a boy name)
Cherry Bomb (Da Bomb I thought that could be cute)
Marbles (This is one of my favorites out of all these)
King Arthur
Merlin
North Star (Star is my other favorite for a girl)
Jingle Bells (Great Christmas name)
I hope this helps. You might see more that catch your eye. This is the link that I used.
