Regurgitation help?

[Bogertophis]

...I've only had her for just under a couple weeks. I've been waiting 2 days before handling after food

OK, while I agree with the above posts' advice for regurges, this ^ ^ ^ ^ ^ really jumped out at me.

You really shouldn't be handling a snake that you've only had for a couple of weeks...not at ALL, for best results, & especially now after regurges.

Standard recommendation for new snakes of any age, but fairly critical for young snakes as they don't have any "reserves", they're just hatched or born:
No handling until the snake has fed easily for at least THREE consecutive feedings at normal intervals, which if you have a hatchling, would be roughly a week between
each meal, plus a couple days to allow good digestion. And it's also best to NOT feed a snake you just got, until they've had a chance to "acclimate" ie. settle in, relax.

So if you were playing it safe, you'd not be handling a new BP hatchling (or young snake) for at least the first month, until it has established an eating pattern. Because
eating is job #1. Without food, a snake will die...though not right away. "Taming" can wait, snakes are living creatures that are instinctively frightened of humans, & fear
causes stress, which is no good for their appetite. So if you want this snake to survive, please, no handling for a while, until she's on track. You wouldn't be here if you
didn't want the best for her...
