Describe Josephine's relationship with her mother ?

Christina is Josie’s mother and is very protective of her daughter. Her relationship with her mother can be strained, but she clearly loves both her and Josie. She never regrets getting pregnant unexpectedly, even though Michael Andretti left her high and dry and to this day refuses to acknowledge his daughter. She is a sweet and caring woman who had her own dreams before her unexpected pregnancy, but always says Josie was worth sacrificing them for.
