She didn't know how to handle her kids' bad behavior. She cried throughout this episode about how helpless and clueless she felt about how to properly discipline them.
However she was very strict and very rude when it came to disciplining especially disciplining Hailey. When she punishes Hailey for her behavior, she would ground her, give her random punishments, and shaking her pointer finger close to her face. When Hailey sees her mom's shaking pointer finger towards her face she would push it away to make the shaking finger in her face stop. Meanwhile Camryn and Matthew seems to get away with their bad behavior (most of the time).
She was 38 years old at the time and now 48 years old in 2017.
