Britney hiring medically-trained nannies

Pop singer Britney Spears is hiring two medically-trained nannies after her baby cracked his skull.

The singer has spent days talking to specialist agencies to find 24-hour care for six-month-old Sean Preston. He suffered a suspected fracture when his chair collapsed at Britney's Malibu home. The nanny caring for him woke Britney, 24, and a doctor was called. He found no problems. But six days later Britney rushed still-groggy Sean to hospital.

"She doesn't want to risk anything happening to him again," a source close to the singer was quoted by The Sun, as saying. "She has been looking for somebody who can recognise the signs if he becomes ill again," she added.

The insider added that Britney and hubby Kevin Federline, 28, were considering installing a sophisticated video surveillance system so they can monitor Sean while away working.
