Seven-year-old Lily-Grace Hooper was told she could not use her cane at Hambrook Primary School in Winterbourne Down near Bristol.
Her mother Kristy Hooper said she was "devastated" when she was told of the decision last Thursday.
The school stressed the measure was a temporary one while the situation was discussed with the family.
Ms Hooper, who first spoke to the Bristol Post, said her daughter suffered from severe sight impairment after she suffered a stroke at four days old.
She had been using the lightweight cane in school since April without issue, her mother added.
"When I picked her up on Thursday her teacher said... Lily-Grace could no longer bring her cane into school. I was quite shocked," Ms Hooper said.
"Lily-Grace is quite sad because she likes to use her cane because of the independence it gives her."
Head teacher Jo Dent said: "The pupil has not been banned from bringing in their cane, we have simply asked them to not use it around school as a temporary measure until we have the chance to meet with the parent and discuss the situation.
"It was initially hoped we would have this resolved within a day or two.
"The school's mobility officer raised health and safety issues around the new cane following a recent risk assessment.
"We have to consider all of our pupils, so it is important that we have an opportunity to discuss the situation before we make any decisions.
"We are very keen to resolve this issue as soon as possible and have been actively seeking to engage with the parent to bring this to an agreeable conclusion."
Geoff Cox, from the Health and Safety Executive, said there was nothing in HSE regulations that would stop a child "from using a walking stick in school".
He said it was up to those involved to work out "sensible" arrangements.
"I hope common sense prevails here," he said.

The trailer concludes with a shot of Vader and the sound of his trademark heavy breathing.
Felicity Jones stars in Gareth Edwards' film as the leader of a Rebel mission to steal the plans for the Death Star.
The film is set before the time of the first Star Wars film A New Hope, released in 1977, and does not form part of the main series.
The two-minute promo, which is different from the one shown at last month's Star Wars Celebration event in London, begins with new character Saw Gerrera (Forest Whitaker) telling Jyn Erso (Jones) that "the world is coming undone".
"Imperial flags reign across the galaxy," his voice continues over a shot of an Empire vessel floating above a desert landscape.
The trailer goes on to show Jyn and Cassian Andor (Diego Luna) being told about the mission for which they have been selected.
Subsequent scenes feature a new robot character voiced by Alan Tudyk, a blind warrior played by Hong Kong action star Donnie Yen, and an Imperial Walker being struck by a missile.
Actress Alyssa Milano, screenwriter Max Landis and DJ Edith Bowman are among those to welcome the new promo on Twitter.
US publication Entertainment Weekly, meanwhile, has assembled a frame-by-frame analysis.

The baby died about six weeks ago but few details of the case were released.
The child was born in Midland Regional Hospital, Mullingar, County Westmeath, on 16 August and died on 22 August at Dublin's National Maternity Hospital.
The Health Service Executive (HSE), which runs the Republic of Ireland's public health services, confirmed it was investigating the "tragic" case.
In a statement to the BBC, a spokesman said: "The HSE incident management policy is being followed and a full and thorough investigation into this tragic event has commenced.
"The family are involved in this process. The hospital extends its deepest sympathy to the family," he added.
