Since she was a little girl, she had a dream of raising a family of 12 children, and was determined to not let anyone, including her husband, "pop that dream."
She would also fly off the handle when she felt the elder kids (Logan, Carley, Chaslyn) weren't doing their job keeping the younger kids in check. Jo was angry that Amy pushed the responsibility of the younger children's safety on the older children in this way, since it's Amy's job as the mother to keep her children safe.
Amy didn't trust Dale to help out more with the children, leaving Logan to act as the father to the younger children. She admitted this was because of trust issues related to Dale's drinking.
After Jo left, Amy had her 11th child, a daughter named Jocelyn Joy Costello on October 2, 2009. 12th child Johnny Costello on March 7th, 2012.
She was 42 years old when she appeared on Supernanny and as of 2017, she is 51
