The Maasei Hashem on Hagadah says that the four children were:
Chacham – Yitzchok
Rasha – Eisov
Tam – Yaakov
Sheina Yodea Lishal – Yishmoel
Yitzchok asks a smart question above. Eisov asks why these belong to you? He was jealous. Yaakov was asking what is this of Lavan when he saw Leah istead of Rochel. Yishmoel did not ask but his belief needed re-enforcement.
