Efraim & Menashe

Why do we bless our sons to be like Efraim and Menashe, of all people? Our daughters are blessed to be like the Imahos, so why are our sons not blessed to be like the Avos? Rabbi Asaf Prisman brings an answer from Chazal and the Targum Yonasan, and then a halacha in the Rema that the Vilna Gaon traces back to baby Moshe refusing to nurse from the Egyptian women. It is a talk for every parent thinking about schools, friends and the world our children grow up in. He ends with a mashal of the Chofetz Chaim about travelers on their first train ride, who paid for good seats and then followed the wrong crowd, and what it says about remembering who we are.
