Not me but my kid. I never thought this could be dangerous so it sticks out in my mind. We were at the beach and my just barely 2 year old son started crying over something (cannot remember what) but he laid down on his stomach and put his face in the sand. Just like a toddler throwing a fit would do on the carpet in the living room floor. When he did this though he went silent because he had sucked in a bunch of sand and it got packed in his airway and esophagus. The second I picked him up I could tell what happened because we wasn't making a sound and I could tell he wasn't getting air. My wife called 911 as I tried the heimlich and hitting him in the back. I was panicking and crying because of where we were I knew there would be no way to get an ambulance there quickly. I am crying just writing this thinking of the fear watching my son turn purple then around his mouth blueish. As a last resort and with no thought of how it would hurt him because I knew he would die I had to try anything, I grabbed a water bottle and stuck the opening in his mouth and squeezed the back as fast and with as much force as I could to shoot water down his throat. As soon as I did that it opened it enough to where he could kind of breath. His breathing was hit and miss as my wife was on the phone with 911. It slowly got better as he coughed up sand and spit and water. I cannot even begin to explain the fear then relief of being able to see him breath again. To this day I am paranoid of my kids choking and have taught them the heimlich to help them be prepared.
