The amount of breastfeeding that establishes its rulings

I was breastfed by my maternal grandmother, who is my maternal uncle’s mother, along with him. Do my daughters have to observe hijab in front of him, considering that I was breastfed more than five times?
If you were breastfed by your grandmother five known times, you became her son, and her children became your brothers, both older and younger. Since they became your brothers, they became the uncles of your daughters. Therefore, it is permissible for your daughters to uncover themselves in front of all your maternal uncles.
