Two different women named Hannah Cohen both gave birth to twins in the same hospital on the same day at Mayanei Hayeshua Medical Center in Bnei Brak. The maternity ward staff admitted the two expectant mothers to different floors of the hospital in order to avoid mixing up the babies. In the end, they didn’t really need to go to all that trouble. One mother gave birth to two boys and the other to two girls.
