Congrats on getting your new snake to eat for you already, yay!
Without seeing the "head wobble" I'm not sure exactly what you mean, but it occurs to me that maybe your BP was extending his head & neck vertically while swallowing?
If so, that might explain the wobble: snakes (& especially young snakes) don't have a lot of vertical muscle strength in their neck, but I've seen snakes do this now & then.
If that's not what yours did, we'll need a video...![]()
