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?

Yes, my boy will have a protocol to nurse both sides to get satisfaction. I think it is just a habit for my boy since young, around 4 months old. Normally I notice although he is full after one side, he will still nurse another side for a while to get comfort. However, for my daugther she only nursed one side each time.
