High Chair, High Drama: Don't even think of saying "hit" and "baby" in a sentence one more time. Especially after Star's exclusive cover story about Britney Spears and Kevin Federline's son Sean suffering a fractured skull and blood clot after being dropped by a nanny as his high chair collapsed. The worried parents took the kid to the doctor pronto, who pronounced him A-okay, but days later, Britney noticed Sean's sleeping pattern had changed and rushed him to hospital. Give Britney credit for some observant mothering. A visit from child-welfare authorities to check on the kid afterward was "routine," a word seldom used to describe life in the Britney universe.
