After finding out that the eruv was broken, I hope they came back after Shabbos to bring home the baby in the stroller.
Maybe you misunderstood, there were 2 Eruv. The greater Monsey Eruv and the Viznitz Street eruv (Or something around their small area where they lived) It was the smaller Viznitz eruv that was down, not the greater Monsey Eruv.
The people I was with were not chassidish
