Alligator Attack: But for the Grace of God ... Another Child at Risk

A little boy was wading in the lagoon at the Disney's Grand Floridian Resort -- in the exact place where an alligator put a 2-year-old in a death grip -- just 30 minutes before the attack.

Jennifer Vendetti and her son, Channing, went to the lagoon around the same time Lane Graves arrived. It appears Jennifer was okay with her son wading in the lagoon, despite the sign that warned people not to swim. Fact is ... he wasn't swimming -- he was wading.

As TMZ first reported, there were no signs warning of alligators, despite the fact that alligators populated the lagoon, and other resorts specifically warned guests of the reptiles.
