So a 3-year-old got expelled from preschool for saying...

If all kids who did this were expelled from preschool, childcare centres would be empty.

We all know our toddlers aren’t perfect but every parents lives in dread of the day that our perfect little children drop their first swearword in front of other people.

Normally we get a call from their preschool, letting us know what happened and the action they took. Most childcare workers will sit down with our children and talk about words they are allowed to use and those they are not allowed to use and that’s it.

But a preschool in San Antonio in the US has taken it much further.

The Jubilee Child Development in San Antonio in the US has expelled a three-year-old girl for saying "sh*t" while playing with her friends. Ariana Wright's mum Cassandra has no idea where her daughter picked up the curse word and while she understands the incident is serious, is shocked they've dismissed them so coldly.

"I'm still a little bit upset, but most of all was hurt, I was devastated really hurt," she told News 4. She says that not only does she feel their action was harsh but that she expected more of a daycare centre that is faith-based.

The centre claims 13 other children heard the word and some started repeating it, which prompted their harsh action.

The director of the Jubilee Child Development Center Alissa Blankenship says there's a zero-tolerance when it comes to saying a curse word. "Well as a private center and also a parent myself you know there's decisions and choices that have to make," she said. "I didn't think that this would be an isolated incident either."

And Arianna isn't the first student to be expelled for swearing. It happened to another child several months ago.

Children pick up swear words, they just do, and sooner or later we are faced with colourful language being parroted by our adorable little cherubs. If children are expelled for swearing when they are two young to even understand what they are saying, then all we can say is that there won't be many kids left in preschool.

Also, is swearing the worst a kid can do? If they are expelled for swearing then what about when they throw sand in the face of a child, pull their pants down and flash the class, hit another child or throw a toy at someone's head. Ask any childcare worker and they'll assure you these are weekly if not daily events.

Raising children is a learning process for us and for them and when we send our children to childcare we expect a partnership to occur between us and the childcare providers.

Do you think this preschool reacted too harshly? What is the worst thing your child has ever done at preschool?
