[Avodah] Inviting Someone On Shabbos Who Uses the Eruv when You Don't

[Prof. Levine]

We have several Eruvim here in Flatbush. I do not rely on any of them.

Question: May I invite a couple whom I know will wheel their baby in 
a stroller to eat at my house on Shabbos?  They, of course, do rely 
on the Flatbush eruv [at least one of them].
