Sydney Dianne Simmons (born April 6, 2005) is the fourth and youngest child of Debra and Tracy. She has an older brother named Payton and an older sister named Sophia. Sydney also has a fraternal twin brother named Parker.
Like Payton, she is also defiant but she sometimes can be aggressive and throw temper tantrums. She was described as being out of control although she was not as bad a Parker. Also like Payton, she was sent to timeout once, but she went there for refusing to put her shoes on while she was outside during teaching, and then she wasn't seen back in timeout since that day. She was 4 years old at the time and is now 13 in 2018.
