i don't know if this count But weezy Jefferson would be my favorate mother or maybe Grandmother.

This isn't a sitcom, but I thought Olivia Walton was a good mother.

Without a doubt it is Mrs. C from Happy Days!

Favorite grandmother's:
Clair's mom on the Cosby Show
Kathryn Romano - One Day At A Time

Favorite single moms:
Kate McArdle - Kate & Allie
Ann Romano - One Day at A Time
Alice Hyatt - Alice

Favorite step-mother:
Sandra Sue "Abby" Abbott Bradford - Eight Is Enough. I liked the way Betty Buckley played her. She was more the children's friend and not trying to be their mom nor trying to replace Joan. She was more of a mother towards Nicholas because he was 8 at the time that her and Tom married. You can see they had a special relationship. Her and Mary, the oldest daughter, had more of a special sisterly relationship. She confided more in Mary about issues she had with the family and in her life.
