Does child support change or lessen if my daughter is now living with me/school and only see's her mother 3 months out of the year?

My daughter's mother is moving out of state (end of June) and wants my daughter to change her mailing address to the out of state address. My daughter is 20 and will be starting her 2nd year in college come August(2019). She'll be living with me and living at school during this time. She'll be at her mother's during the Christmas holiday, which is a month. She'll go back to her mother's(maybe) during the June and July months as of now. This may change if she's working a paid internship here where we live during those months. She'll be with her mother 3 months out of the year, (again, all depending on internship status) the rest of the time during the school year she'll be with us and school. And, if my daughter does decide to stay with me during the Summer months as well. NOTE: we were never married. My question above. Thank you in advance.
