In a lengthy Facebook post that has been shared thousands of times, the mother-of-two claimed the centre had not called an ambulance or provided adequate first aid when her son's big toe was slammed in a door.

However, the centre said the mother was contacted immediately and the child was collected within 20 minutes of the accident occurring.

In the Facebook post, the mother said the centre covered the injury with baby wipes and called her to come and pick him up saying he needed to be seen by a doctor.

"I received a phone call while I was at work from the centre," the mum wrote.

The mother claimed the centre advised her the child's "toenail seems to be lifted and there is a small cut and lots of blood and my son will need to be seen by a doctor".

She said she had not realised how serious his injuries were until her sister picked him up.

"We discovered after pulling the baby wipes the centre placed over his toe that his big toe was 50 per cent detached," the mother wrote.

"We immediately dialled triple-0 for an ambulance from home."

The mother said her son was taken to Queensland Children's Hospital in Brisbane where he underwent surgery.

"We are still awaiting to find out if any further damage was found," she said.

"My son will have a long road of recovery and won't be attending child care for a few months but is enrolled to start at a new centre when he is given the all-clear by doctors.

"[He] is still in shock. He cannot play with his brother or his family, can hardly walk around, let alone run."

The ABC has unsuccessfully attempted to contact the mother to verify the details in the Facebook post.

First aid applied immediately, company says

The childcare centre is owned by G8 Education Limited, with a spokesperson saying in a statement that first aid was applied to the child at the time of the incident.

"On the morning of Monday, September 16, a toddler's toe was accidently jammed in a storeroom door," the spokesperson said.

"[Staff] immediately took action to apply first aid. Without delay, other team members lent their support to soothe and calm the child.

"The incident was reported to the relevant regulatory authority, who are investigating."

The spokesperson also said safety was the centre's top priority.

"Our sympathy and thoughts are with the family and their little boy following this unfortunate accident," the spokesperson said.

"The parent was contacted immediately and the child was collected within 20 minutes of the accident occurring.

"We have also been in contact with the family since to offer our full support.

"Our team reacted swiftly when the accident occurred with our primary objective being to care for the child. The safety of our children is always our most important priority."

In a statement, a spokesperson for Queensland's Department of Education said the matter was being investigated.

"The safety and wellbeing of all children is the highest priority for the Department of Education," the spokesperson said.

"Regulatory staff in the South East Regional Office of the department will be assessing information provided by the child care service.

"In addition, regulatory staff will conduct a visit to service to check the physical environment and practices of staff to ensure that the approved provider has taken all reasonable steps to protect children from harm and hazard.

"Based on their investigation, regulatory staff will determine an appropriate response, and respond to both the complainant and the approved provider with the outcome."
