Milk Production

Hey ladies,

Is it normal for your milk production to be less during the day (after 12pm)? My almost three month old can be content with one breast between the hours of 11pm-12pm but has to have both breasts the rest of the time.

My boobs get full every 2-3 hours at night, but during the day I feel like it takes them a bit longer. She gets frustrated when she empties one boob, and that’s when I switch her to the other (sometimes she gets frustrated on the second one as well :(

Any advice?
