This child is very adorable but indeed acting like a normal and typical child for his age. Children need to be allowed to express themselves by whatever means necessary even if that means a little back talk. As a social worker, I find it important to note that this mother is using spanking as a punishment that is not appropriate for any child under any circumstances. Time out and reviewing what happened and explaining why the incident was wrong is appropriate. I cannot tell you how often I see children removed from homes because of stupidity upon parents to properly control a child. Stealing a cupcake is a classic sign of this child exercising their personal empowerment and if the parent had properly expedited her authority by means of reasoning the conflict wouldn’t have happened.
