AURORA - A mother in Aurora claims a teacher at her child's preschool, Children's Academy, refused to let the little girl eat part of her lunch, because it wasn't nutritious.

As school officials attempt to get to the bottom of the issue, Leeza Pearson is upset that her child was not allowed to finish part of her lunch.

Pearson packed her 5-year-old daughter a ham and cheese sandwich, string cheese and a 4-pack of Oreos Friday. The child came back home from school with a note from her teacher which read, in part:

"Dear Parents, it is very important that all students have a nutritious lunch. This is a public school setting and all children are required to have a fruit, a vegetable and a heavy snack from home, along with a milk. If they have potatoes, the child will also need bread to go along with it. Lunchables, chips, fruit snacks, and peanut butter are not considered to be a healthy snack. This is a very important part of our program and we need everyone's participation."

The Oreos were still in the lunchbox when Pearson's daughter returned from school Friday. The child said her teacher didn't allow her to eat the cookies during lunch, because they don't have enough nutritional value.

Questions over the note remain. The director of Children's Academy said she's investigating the note, adding that it should not have gone out to any parent. The director said it is not school policy to tell parents what children can or can't eat for lunch.

A discussion will be held with the teacher Tuesday, the director said.

Pearson is concerned this points to a larger issue.

"What the school thinks is healthy for her is not what I think is healthy for her," Pearson said. "That's between me and her and our doctor - not the school."

Since the school receives funding through Aurora Public Schools, the district says it also plans to look into the matter.
