Smacking lips? Gnashing teeth?
My big boys get into some good wrestling matches (my mom calls it 'sumo wrestling' ), and Cole is the one that makes this sound. He opens and closes his mouth a little ways - looks and sounds like he is smacking his lips.
Oscar doesn't do this.
Anyone seen this? I am sure it is a part of the play fighting, but wondered what it was.
