Very sorry to hear about all the flooding. As someone who lives though natural disasters annually, a tip for those that want to help from afar:
Find the mailing address for a local shelter that’s directly assisting (maybe someone here that’s local could assist with an address), and use your Amazon account to mail stuff like socks, diapers, toothbrushes, etc to them directly. Louisiana shelters have learned to publish wishlists of stuff they need after hurricanes, so check for that. If you’ve got a prime account, it’s generally there in 48 hours.
Hoping for the best for all involved.
