PORTLAND — Parents shopping online for child care aren’t the only people Oregon regulators leave out of the information loop. Sometimes, state officials fail to notify existing customers when problems arise at a facility.That’s what happened this year when the Office of Child Care tried to shut down an east Portland day care called Sugar Pine.Regulators intervened after the owner and licensed child care provider, Sarah Herbelin, admitted using illegal drugs, state records show.Regulators wrote that Herbelin told them she never used opiates around children or when her in-home day care was open. She also told regulators she completed a treatment program, state records say. She declined to comment for this story.State officials considered an emergency license suspension. Parents would have been notified if that happened, said Lisa Morawski, an Office of Child Care spokeswoman.But regulators worried a suspension wouldn’t hold up legally. They opted instead not to renew the facility’s license when it expired in January. Morawski said the state does not inform parents of non-renewals.
