"I had already been debating whether or not to send my child to daycare prior to lockdown and reluctantly I did, as I work fulltime," she said.
"You can imagine how guilty I felt as a mother when this letter had come through."
Eyre said other business and organisations who have had a staff member test positive to Covid-19 should take advice from public health officials, who will have investigated every case.
"The job of the team is to assess every risk and make sure no stone is left unturned in following up Covid-19 contacts. We have a duty to do that and will make sure that information is transparent and clear when there is any wider risk to anyone."
An Early Childhood Council spokeswoman said following government advice and continuing the hygiene guidelines are essential.
"Essentially, our message is to follow official advice," she said.
"Before the lockdown, we strongly recommended all children and staff stay home if they weren't feeling well, washed hands regularly and regularly cleaned surfaces with chlorine-based cleaning agents.
"We support everything the Government is doing to stop the spread of Covid-19."
