Choose a place which would be a tradeoff between proximity to work or Uni for you and family members who move with you. Ideally, all of these places should be located in an optimized way, reducing total time spend on commuting. If such a location isn’t feasible (e.g., there are no schools close to your workplace), choose a place from which you could walk to at least one of the locations and commute to another.
If you have an option to work from home, utilize it, and choose a location closer to the school (total commuting time reduced, since you won’t travel every day to work). You can also look at internet forums for parents whose children attend the same school as yours and share school dropping responsibilities.
