"After Midnight" host and country singer Granger Smith and his wife Amber lost their 3 year old son River to a drowning accident at their home in 2019. The couple has been strong proponents of making sure your children know how swim from a VERY young age. He posted the video below on Instagram with his 8 month old son Maverick, saying in the post, " Thinking that adult supervision is enough is an absolutely DEADLY miscalculation. Hear me. I used to think that too." What you will see in the video is hard to watch, especially if you're a parent. Granger credits his wife Amber for being present at these ISR (Infant Swimming Resource) lessons, as he couldn't "because of my own vulnerabilities". With summer right around the corner, this might be the most important thing you read today. Granger knows that saying, "Only ONE person needs to see this, and hear my plea to you. Drowning is the #1 accidental death of children age 4 and under." Click HERE to find ISR instruction near you.
