Breastfeeding

Melissa
Since birth my son Maddox has been a "lazy water" sucking down 4-5 gulps them falling asleep, he is now 5 weeks old and still doing it. Anyone else have this problem and any advice. I pump since he isn't emptying me all the way so I have a freezer full. And yes he is gaining weight he just tends to feed a lot and small amounts bc he falls asleep
