HG Schild asks:
If 4 brothers where two are married to two sisters and the two brothers diie I follow zikah etc that the remaining two cannot marry the two widow sisters... BUT WHAT IF BOTH SISTERS HAVE CHILDREN from the dead brothers Can the two brothers left marry each to a sister?

The Kollel replies:
Shalom R' Chaim,
Great to hear from you.
Forgive me for pointing out what you might already know, but discussions of Yibum and Chalitzah typically assume there are no children (Devarim 25:5). If there were children, each surviving brother would be forbidden to marry either widow because of the prohibition of Eishes Ach (Vayikra 18:16).
I hope this helps!
Warmest regards,
