My 7 week old son has been doing fine with breast feeding. He has always been very anxious to get as much as he can out of both. Now all of a sudden for the past few days, he eats off one and then is completely uninterested in the other. I try everything to get him to eat but he will not open his mouth. He just looks at me. He seems satisfied and full. Of course I am also worried about my supply since he has now made himself block feed. Should I worry?
