Nadya Suleman has checked herself into rehab for a prescription drug problem ... leaving her 14 kids without a mother for 30 straight days ... TMZ has learned.
A rep for Octomom tells us ... Nadya admitted herself into the Chapman House Drug Rehabilitation Center in Southern California over the weekend after acknowledging she's become dependent on Xanax ... an anti-anxiety drug ... which she began taking to "deal with stress."
Suleman's rep tells us, "Nadya wanted to get off the Xanax she was prescribed by her doctor and learn to deal with her stress, exhaustion and anxiety with professional help with a team of doctors. Nadya wanted to deal with her issues and make sure she is the best mother she can be.”
TMZ has obtained photos of Nadya on her way to the treatment center (above).
As for the kids ... we're told Nadya is using 3 nannies and 2 friends to divvy up the child care duties. She also has a driver to take the kids to and from school.
Neither Nadya's mother nor father have been tapped to care for the kids.
We're told Nadya can afford to pay for treatment by herself -- because she's been making a ton of money from her porn career -- but the rehab facility offered to pick up the tab anyway.
