Does a niece become a sister to her maternal aunt's daughter through fosterage if she consumed food mixed with her aunt's milk at the age of four?

The girl is not considered her sister through suckling for two reasons: First, the suckling that prohibits marriage must occur within the first two years of life, and this girl was suckled after that period. Second, what she consumed of food mixed with milk is not considered suckling unless it consists of five satisfying sucklings.
