Sources tell TMZ the L.A. County Department of Children and Family Services "abuse investigation" into Britney Spears does not involve physical mistreatment of her children.
Sources say the complaint lodged with DCFS involves allegations of poor dental hygiene, as well as poor eating and sleeping habits for her kids. Curiously, although DCFS keeps these allegations secret, they ended up in legal papers filed today by K-Fed's attorney, Mark Vincent Kaplan, suggesting it might have been Fed-Ex himself who lodged the complaint.
And get this: DCFS is all too familiar with the family. We've learned that another anonymous complaint was filed with DCFS on July 2, but it went nowhere.
Sources say DCFS has put both Britney and K-Fed under the microscope in the past. In February, 2006, DCFS famously investigated Britney after the notorious car seat incident with Sean Preston. Ditto April, 2006 (while Brit and K-Fed were still together), after Sean Preston fell out of a high chair -- another DCFS investigation came and went.
