Anytime within four to six weeks is when kittens start eating food because it’s easy for them to consume and digest. If their mom hasn’t done so already, lead them to the dish and gently put a smidgen of food on their mouths a couple of times.  Actually, it’s OK to have them try kibble during this timeframe, too, as long as it’s moistened with a 1–to–3 ratio of warm water to food so it’s a little soggy. As their teeth continue to mature, they’ll be able to crunch to their heart’s content.
