My 2 week old daughter has been eating about every 2-2.5 hours. I do not switch breasts because that usually made her not interested anymore. Letting her stay on the side she starts on she usually doesn't pull away until 20-30 minutes. She doesn't suck the whole time but is that the "normal" time for them to nurse? Just wondering..
