Prepping for Young, Pregnant, or Disabled People

This is a topic that gets underlooked in prepping circles I think. Probably because it's such a challenge. In some cases the only option is to 'bug in', and I'd say that's always the preference if at all possible. But sometimes you don't have a choice. Maybe it's a wildfire that springs up suddenly, or a post-collapse group of bandits that you see coming and you need to run. What do you grab? How do you prepare? For my post I'll say 'young' people is 5 and under.
