The main mistake with hognose is that people will under feed hatchlings not realizing that they have a fast metabolism and that at first the prey offered is not very meaningful.
Hatchling should be fed every 3 to 5 days, once they reach a year old every 5 days and adults can be fed every 7 days.
You can expect an hatchling to reach 50 to 100 grams in his first year depending on the sex, sadly you often see 1 or 2 years old weighing in at 25 grams instead.
All my hatchlings from this year are already nearing 20 grams simply by being properly fed.
Yes you want to give them at least 24 hours to digest for the same reason of possible regurgitation.
