"All we're hearing right now is that there is no change there's a lot of swelling in the brain," says Nathan's grandmother Donna Bay.
Bay says the young boy wandered off during a family get-together at his great grandparents' house on northwest 65th street.
When the found him, he was pinned underneath the gate, which was leaning up against the house.
He was found unconscious and not breathing and was transported to the hospital.
Family members say they are "cautiously optimistic" that he will pull through.
