A MUM stabbed in front of her three-year-old daughter at Notting Hill Carnival may lose her leg, a court heard today.
The 32-year-old had stepped in to help after a fight broke out when she was knifed in the leg, it is alleged.

She was rushed to hospital with life changing injuries and remains in a critical condition.
Three brothers appeared at Westminster Magistrates’ Court today following the horror.
Shakiel Thibou, 20, who is charged with attempted murder, had allegedly attempted to stab the intended victim while armed with a “Rambo-style knife”.
He is then accused of knifing the mum – causing her to go into cardiac arrest.
JPs heard she lost 20 litres of blood in the horror attack and suffered a collapsed lung.
She remains in an induced coma and may never recover, the court was told. The mum could also lose her leg.
Thibou, who is also charged with violent disorder and possession of an offensive weapon, claims he was attacked.
His brothers Sheldon Thibou, 24, and Shaeim Thibou, 22, appeared alongside him in the dock.
Both are charged with violent disorder and assaulting an emergency worker, while Sheldon faces an additional charge of possession of a stun gun.
The court was told all three brothers were involved in the horror but just Shakiel Thibou carried out the stabbing.
Prosecutors say they attended the carnival with the intention to cause the intended victim harm.
The trio were remanded into custody to next appear at the Old Bailey on September 25.
