She worked as a teacher, while her husband worked from home and looked after the kids. When she came home, she would go right to work with parenting and housework, even cleaning the house after all the kids had gone to bed.
Even though she knew she was doing too much work herself and Michael's child care routine left something to be desired, Joanne did not want to hire someone to look after the children. She felt that Michael was the next best option after herself.
She was 30 years old at the time and is now 43 in 2017.
Sometime after "Supernanny", Joanne had another daughter, whom she named Elizabeth.
