For hatchlings, I've found that hides can be the difference between eating and holding out.

I offer rat pinks first, then if they don't take it from the tongs, I put in a hopper immediately after, they almost always take it. I usually have about half take the rat pink 1st try and the rest take the hopper. Of course there always seems to be one stubborn one.

If they don't eat, rinse and repeat once every 5 days. Except, if you're using rat pinks, scoot the pink into the hide with the snake and leave it for an hour or two or even overnight. If they don't take the pink, follow it with a hopper, they'll usually snatch it right up.

As you can tell, I always try rats first, just because that is what I want them on in short order anyways. Some don't try rats until after a meal or two of hoppers. Whatever works for you.

Also, try feeding at night and keeping it as dark as you can while feeding.

I'd give it a couple more weeks before you start thinking assist feeding personally.
