Breast Feeding Moms...?

When I had kids I did not breast feed. However, a friend of mine just had her baby. He was 9 lbs. at birth. She will only feed him every three hours. I thought if you breast fed you did it on command. Both times I have seen him, he has been sticking out his tongue and fussy. Which would have meant with my daughters they are hungry. I said I think he's hungry. She told me he had another hour before he could eat again. Now, here comes the best part... She is training him to sleep through the night and skipping his nightly feedings so he learns to sleep. Remember he is only 5 days old. Is this something that sounds normal? It sounds totally ridiculous to me. She is starving him for six hours. Also, the nurse told her husband to have him suck on HIS nipples so he can have the bonding with the child. I think they have gone insane. My daughter was 10 pounds at birth and she ate up to 4 ounces every two hours some days. Does this sound crazy to you too?
