A woman with a rare condition that means she collapses every time she laughs fears she may have passed the rare illness onto her young son.
Kelly Timson cannot visit a comedy show or even go to the pub with her friends as every time she laughs, she collapses in a literal fit of giggles.
She suffers from a rare neurological condition called cataplexy which means her body goes into a state of total paralysis in response to strong emotions such as amusement, surprise, anger and even love.
Just gazing in motherly admiration at her two young children Charlie, five, and Ronnie, two, brings on an attack leaving Kelly totally unable to move or speak.
Often, she finds herself collapsed in a heap on the floor having injured herself on the way down and once she nearly suffocated after landing face-down on the sofa.
She suffers up to 20 cataplexy attacks a day and has to have her mother or brother around her all the time in case she collapses.
She also suffers from the related condition narcolepsy which means she randomly falls asleep throughout the day, no matter what she is doing
