Octomom's Oldest Son Gets Restraining Order Against Nanny

According to legal docs ... Gina Bryson has been incessantly harassing 11-year-old Elijah Solomon with phone calls and text messages.

Sources close to Octo tell us, she fired Gina over the summer -- and that's when Gina allegedly began her campaign of calls and texts.

The docs accuse Gina of leaking false stories about Elijah to the media. A judge has prohibited Gina from going within 100 yards of Elijah, or contacting him in any way.
