Could my breast milk be running out? My son is 5 weeks old and acts starving even after I breastfeed him. And hasn't been sleeping well. There were some good nights rest up to 4-6 hours at a time and he was sick but now idk I feel like he's not getting enough milk from me... i don't understand. I just gave him a 2oz breast milk bottle and he's slowly drinking it and slowly looks to fall asleep finally.
