Regarding the baby formula, bear in mind that people will need clean water, possibly bottles and a heat source / sterilization too …. And while you’re about it there is the other end of the baby too ! I’m not trying to make it hard, but formula on its own is only part of the story.

Seems like you already have a great community established, so perhaps what you could work on is building a community response plan to an emergency. Sounds like you have school buildings / community buildings within your neighbourhood, so you could call a community meeting and try and get a few people onboard to help with a neighbourhood plan. You may even be able to raise funds to buy communal facilities like a large generator, emergency blankets, long life food, or giant bottled gas etc items to equip the school as an “evacuation centre” …. You may even find a space that you could stockpile items ?
