In my ex pil village they would do this sort of thing. But because it was a fairly secluded village, where the community was very close. In winter they could often get cut off for the main roads so did rely on each other. Not everyone was involved, especially as the village grew and not every body knew eachother.
But it was usually organised by the village council. No one fairly, new moved in and started asking for people to provide meals.
You got added in by signing up. Usually someone from the village council would spread the word. You went to the village hall and signed up for a certain day. If you were new to village and signed up, they would also make sure they looked after you.
Though in winter everyone just helped everyone.
If you were new in the village but been helping other people, someone would offer as soon as they knew you were pregnant. In your case you probably wouldn't have had chance to help out, if the baby came soon after or before moving.
It was a lovely community, if not a bit suffocating sometimes, but it certainly wasn't someone knocking on doors asking for meals to be delivered. The HV seems confused
Are you struggling to feed yourself? Are you needing some support?
