My dd is on no schedule. Sometimes she goes 2 hours sometimes half hour before wanting to nurse again. Also her actual eating time is 10 minutes or so, sometimes a little less, But a lot of the time she will just stay on sucking, but not really eating, So sometimes it will be a half hour or more. At night once I finally have her settled to sleep, she will wake every 2-3 hours to nurse and stay on about 10 minutes then fall back asleep. My last dd was the same way. It took about 2 months maybe 3 for her to finally stop cluster feeding so much and finally settle into a every 2 hour nursing schedule during the day
