1. Create a public event on Facebook.
2. Share your story in the description.
3. Add a cover photo.
4. Set a time and date, it's best to do it within a week or two of the incident.
5. If it's a particularly volatile situation, consider hosting your nurse-in in front of the business on public property. Businesses are legally allowed to ask you to leave if you are trespassing on their property or causing a disturbance with your presence. However, they may not ask you to leave because of breastfeeding (exception Idaho).
