Yes, and that's what the families are telling us. There is nothing else out there for them. There are no other activities in French. They can participate in Anglophone programs, but if they want to continue to pass on their language, that becomes difficult, even more so if the spouse is English-speaking.
Sometimes, at home, if the spouse does not speak any French at all, the couple will use English, which means that the only time the mother and her child can speak French is when they are in the presence of other Francophones. There are no groups offering programs or activities like “repas-répit” or “matin-maman”.
