OP don't worry too much about underfeeding they can go awhile without, even as hatchlings. A schedule is nice, but if you happen to go away for a few days, your BP will be absolutely fine I'll bet!

Also, if feeding out of the enclosure works for you and the snake, keep doing what you're doing! I feed one of my snakes in the enclosure (simply because he gets excitable) and the other outside, and she couldn't care less if we watch her. Even though both are on f/t I also enjoy watching as well, which is why I do it.
