What do you do with your kids in the summer if you work ?

This may be a stupid question but I have no idea how people make this work.

If both you and your husband have day jobs what do you do once the kids are out of school ? Who watches them all summer ?!

My kids are not in school yet but even school I have no idea what we will do because both my husband and I work 9 to 5 and all our parents still work full time as well. Idk how I can get to work and get kids to and from school if drop off and pick up interfere with our work schedules...

HELP what do you all do ?!
