My little girl is 4 weeks old and I've found, at first, that I had an oversupply of milk. My boobs were always engorged, especially my left one. My poor baby would start choking gagging and coughing during my let down phase and even after that. Now it's the opposite happening. She's nursing the same amount of times during the day but she's done feeding after only 5-10 min. I'm worried that this caused a decrease in my supply Bec now my boobs feel empty. My little one also RARELY takes the other breast at each feeding session and I'm also worried this plays a role in my decrease in milk (if that's what this is).

Is the empty breast feeling normal? Is the time feeding normal? She has plenty of wet and dirty diapers. Not sure about weight gain as we only had one doctors visit since her birth. Next one is coming up next week.
