Talk about a bad reaction.
On her first trip with her sons back to Louisiana since she lost custody, Britney Spears' youngest son, Jayden James Federline, was rushed to the hospital for having what Spears' reps deemed a "reaction to something he ingested."
Although the 2-year-old tyke has since been released and declared "fine," it's possible an even worse reaction could transpire, should Kevin Federline seek to restrict Spears' remaining custody rights for the duo's two sons.
"If she was negligent—for example, he couldn't eats nuts or shrimp and she fed him that—then Kevin could go in and get an order modifying custody," L.A.-based family law attorney Lynn Soodik tells E! News.
