Don’t force your feedee to eat eat more than they can hold, we wouldn’t want them vomiting up all their hard work.
Don’t force them to do something they are uncomfortable with, a hesitant eater is a slow eater.
Be sure to compliment them, call them chubby or beautiful! A feedee that feels confident eats with confidence, they’ll be eating every little thing as though they can’t cram it down fast enough.
Get your feedee some small clothes of several different sizes: some that are a little snug, some that are bursting at the seams, and some that show off their underhang just a little bit. Make sure some of these can be worn in public so your feedee can feel huge all day long, prompting motivated eating when they get the opportunity!
