London, Mar 1 : Cancer-stricken Jade Goody's five-year-old son seems to have realized what his mother is going through.

The former Big Brother star's bridesmaid and best friend Jennifer Smith has confirmed that Goody's sons Bobby and his four-year-old brother Freddie know that something is terribly wrong.

Bobby has in fact started sleeping in his mother's empty bed.

"Bobby's been sleeping in Jade's bed. He gets up in the middle of the night and goes into her room, even if she's not there but in her hospital bed in the lounge. He senses something," News of the World quoted Jennifer, as saying.

"He just goes and lays in there on his own. The boys are astute and know something's going on."

"It's so hard trying to work out what to tell them.

"How can you tell your children something like that anyway? Jade's spoken to me about how upsetting it's going to be. It's going to be the hardest job," she added. (ANI)
