How Often To Bottle Feed A 2Bweek Old Kitten?

my 2bweek old kitten is refusing to eat by choice. i haven’t tried giving him food yet, but im worried about when he finally will. do i feed him every 3 hours (like my older cats), or just give it to him at night? what are some other reasons that they may not be eating? how often should you bottle feed a 2bweek old kitten?
