You know what slinging sounds like at my house? It soulds like this:
"Dad. Dad. Hey Dad! DAD! Hey DAD!..."
LOL
I tried to film a practice session a couple days ago, and I got 4 shots in before my 1yo grabbed the camera, pulled it down on top of himself, hit his head, and started crying. That's all the slinging I had a chance to do that day
No worries though. In a few more years my boys will be old enough to sling with me, and I will be one proud papa
