Mouse pinkies or rat pinkies?
If its mice, it's way too small of a prey item to offer. Try mouse hoppers.
And what temperature are you heating the prey to? Blast them with a hair dryer before offering to around 100 degrees.
But if that doesn't work, I suggest trying a live mouse hopper.
And what is your husbandry like? If your enclosure is too open or spacious, it can make a hatchling very very insecure. Insecurity often leads to going off feed.
EDIT: Never mind. I just say your update post. Congrats on getting your snake to eat!![]()
