Hey no worries.
We have multiple friends who have on average around 8-10 kids. Real Eastern European Shtetl salt-of-the-earth types. They all chip in and do chores, babysit as needed, etc. I've taught the middle aged kids how to garden, fish and what local berries and plants are safe to eat. However there are families out there who would rather take what they want by force. A father with a meuling family can be one of the most dangerous threats to anyone with food to eat and supplies to take. Then there's the people who'll be off their meds. <--- there's your screaming zombie horde.
If a large family had all their food/supplies taken they'd be in as much trouble as someone who didn't (or didn't know how) to prepare for an emergency. I have maintained a stash specifically for them in my basement and I also keep a stash for us in their attic.
I have several water sources so that won't be a problem. The reason we drink so much bottled water is because 3 years ago e coli was detected in our cities drinking water and the Water Authority didn't say anything until 3 days later. A lot of people were feeling wonky and they wouldn't even pay the $60 for a new water filter for the refrigerator.
And I also remember the stories my grandmother use to tell me about grown up in Shanghai back in the '20's. I'd ask her all kinds of questions abut how they made it through the day-to-day living. I listened, and I remember. (i.e. weevils are good protein.
