Negative Reinforcement
Every time Marie complained to her mother about her swimming lessons, dirty laundry, or the fun activities she was missing out on, Bridget was quick to turn the tables on her. In these instances, she would point out that it was Marie who was to blame for her predicament since it was her actions that had led to this.
On her Facebook group, the furious mom explained to the other parents that until she found a new sitter, Marie would have to deal with the issues at hand. Additionally, since she could no longer go to her fun activities with a nanny anymore, that also counts as negative reinforcement, right?
