My 15m-old has been nursing differently for the last week or so. She eats on one side for 20 seconds to a few minutes, then switches, then repeats the process on the other side, then switches again. This goes on for 5-20 minutes. She lets me know that she wants to eat on the other side with signing, which is great. I just am wondering if anyone else has experienced this? Is it a game or something to do with milk supply?
