At night, though, I'm not getting that let-down feeling anymore and I'm not hearing the gulping that comes with my milk flowing. Last night, for example, I woke up 3 times to find him still latched on and nursing after an hour but no feeling of any milk coming out and no leaking or wet spots on the other side. This is my 4th breastfed baby so I have experience but have never had this experience or concern.
Is this something to be concerned about? Could my milk supply be ok during the day but low at night even with baby nursing around the clock?
