Crews from Essex County Fire and Rescue Service have been asked to attend two rather unusual incidents today.
They were first called to Westcliff to help a three-year-old girl with a toilet training seat stuck on her head.
Leading Firefighter Ross Danes from Southend Fire Station said: "The toilet training seat was stuck over the little girl's head.
"Firefighters gently prised the training seat off over her head, she was very brave and was unharmed by her ordeal."
Shortly afterwards they were called to a nearby incident in Shoeburyness, involving a child's foot trapped in a cot.
Mr Danes said: "The four-year-old boy was in his cot when he got his foot stuck between the iron railings."
Ten people have been made homeless after an arson attack at a block of flats in Westcliff in Essex.
Officers arrived at Palmerston Road last night after a man threatened to set fire to the flats. They arrived to find the property alight.
The 40-year-old man, who jumped from a window, has been arrested on suspicion of arson and is in a critical condition at Broomfield Hospital.
Southend Borough Council have been helping to re-house the residents.
