Yeah, might be assist feeding time if they won't eat either live or f/t on their own.
I had one baby this year, a twin who was only 37 grams at hatching, who wouldn't do live or f/t. This past weekend I picked him up, put the head of a f/t fuzzy mouse into his mouth, not down his throat or anything, just set the head in his mouth with the body hanging out. I then set him down in his tub and he proceeded to eat it on his own.
Hopefully that will work for your babies as well. Good luck!
