The best rule of thumb for prey size is 1 or 2 items of approx. the same girth as the snake is in its thickest part. I'd guess that from what you said that your snake would probably be fine on small hoppers instead of pinkies. I would not feed it the adults as they sound quite large for your little one & you risk a regurge which is not very pleasent for you & even less pleasent for your snake. Mark I.
