Wow! Sorry to hear that but congrats on the ones that are eating. 20 and 30 grams is frighteningly underweight. Consider triple checking your husbandry b4 you force feed a second time. Check Deborah's "hatchling care 101" which is a sticky. Make sure to give the two of them a bigger water bowl. Don't handle them anymore except to spot clean and not until they have eaten four times consistently. Force feeds really stress the baby. Good luck.
