My 8 month old baby likes to switch from one breast to the other (as if playing) when I nurse her. Has anyone else experienced this?

My baby does the same. And she prefers one breast to the other, which is a bit annoying because she would refuse to latch on one breast. I know a number of mummies who experience the same with their babies. As long as she is thriving well, I don't see this as a problem. And her preferred breast will compensate anyway.
