Atlas and Aiko

S
We find out tomorrow what the sex of the baby is.  We were thinking Atlas for a boy and Aiko for a girl.  If it was a girl I'd probably call her coco puff or some deviation of  "Koko", like coco-nut!! Haha.
But Atlas is much harder.  H don't like the name Atty and I don't really either.  Any ideas for cute nick names for Atlas??
