Nipple tugging!

Marjorie • "Just staying on it I guess, long as she can."
My 3 month old has recently started tugging and stretching my nipples out while nursing. He tugs, stretching it out like a balloon, unlatches, latches back on, then does it again. Is this normal behavior? It's not painful. I think it's kind of funny. It's almost like he's playing a game? Any other Mamas experience this early on?
