Ah memories of breeding season.

I breed childrens pythons and they do the exact same thing when born.

I have used T-Rex lizard maker with stubborn feeders and it worked great. 2-3 drops on the pinkies head and offer it to the snake. I have also had good luck with bagging the snake and leaving it in there overnight with a thawed pinkie in it's cage. The hard part is getting these guys started. Once you do, they are great eaters. Some start right away and others try your patience.

When you say forcefeed, do you mean putting the head of the pinkie in the snakes mouth and they do the rest? That's actually assist feeding and I have done that in the past. If you mean you push the pinky in and massage it down until it reaches the stomach, that is forcefeeding and VERY traumatic to the hatchling and it could cause it's death.
