An investigation is now under way but, surprisingly, the carer who failed to report the incident is still working at the daycare centre involved, Unitec Early Learning Centre in Mt Albert.
Every parent with children at that centre has a right to be worried.
The toddler's father, Curtis Young, is reported as saying there had been a "catastrophic failure" by the caregiver to meet her professional responsibilities and they were meeting lawyers this week to pursue civil litigation.
He said the 24-hour delay in getting medical attention for Jaden could have been fatal.
The parents have noticed Jaden's balance has been affected since the head blow. They won't know if he has any lasting effects for some time, because there is no concussion test for toddlers.
In a letter to the parents, the centre's manager apologised.
ACC figures show more than 1000 children aged up to 4 are hurt in accidents at early education centres every year.
There were 1035 claims in 2010, 1189 in 2011, and 1328 in 2012.
Even more concerning is that the Early Childhood Council, the body that represents early learning centres, says many caregivers are confused about what they should report because they face a bewildering array of legislation to comply with.
Chief executive Peter Reynolds said it was a highly regulated environment that could lead to misinterpretation of the rules and people not understanding what was required.
What rubbish. If a child falls heavily on his head, the parents should be told. This caregiver has breached trust and shouldn't be allowed to continue working.
Such horror stories spoil it for the industry, making parents even more paranoid about going back to work.
Thankfully my Quality Kidz carer (Denise) is wonderful and keeps me more than informed of my wee girl's every mood and mishap - which is how it should be.
