Last weekend, we decided that we need to practice walking the triplets around in public without containment, so we took them to the mall one morning, sans stroller. We chose a Sunday morning before 12 at a local mall with an indoor playground, in order to minimize trouble.
I was mainly concerned about Willa, as she is the one who usually wants to take off on her own, but she was surprisingly great. With the exception of a few unnoticed (only briefly!) escapes from the playground area, she was very happy to behave, and actually walked the entire mall holding hands. We are making progress. Soon we will be able to go out and about like normal folks.
