Outreaching with kids can be fun if you take time to make it fun for them and don't force them to knock on doors. We allow the kids to knock, if they want to. They are partnered up with an adult and have to stay where the adult can see them, but mostly they play nearby while the adults handle the door knocking.
If an apartment has a playground and we have time we always let the kids spend a few minutes there.
Most places have landscaping rocks or walls to climb. As long as it is safe I let the kids conquer the obstacles. Sabrina insisted that I take her picture after she scaled the wall.
If it is fun for the kids there will be less whining and you will get more done.
