A woman in Philadelphia named Dionna Praylow was getting ready to give her three-year-old son Reginald a bath last Wednesday.  And when she went to grab his pajamas, he fell out a WINDOW.

Apparently he leaned on it . . . the plexiglass popped out of the frame . . . and he fell two stories into their backyard.

But luckily a framed painting of “The Last Supper” was sitting on the ground right below the window, which broke his fall and saved his LIFE.  Paramedics took him to the hospital, but all he had was a bruise on one arm.

His family says they’re not sure WHY they had the painting sitting in their backyard, but it belonged to Reginald’s grandmother.

There’s a photo of it online, and you can see some scratches on the front . . . but it doesn’t look like it ripped or anything.

And they’re going to hang it in their living room from now on.
