My DS is 4 weeks now and i have been exclusively pumping since birth. Is it too late to have him feed from the breast? I tried a couple of time and he does latch on (or so i think) and suck. I can hear him swallow so i think he is getting the milk. However, he only last no more than 5 min on one breast then he get fussy (due to slowness of milk?) In addition, my DS sleep ALOT so i don't know when to feed him. By the time he is awake, he is too hungry to have patient for the breast. Help!
