When adding a meal activity on the app, you might see a little peanut icon next to some of the children's profile pictures.
This indicates that the child has something written in the allergy field of their profile.
At this point, the peanut only serves as a visual reminder. You will still need to go into the children's profile and click on the pencil icon in the upper right to view what their allergies actually are.
If you would like that icon to display everywhere on the app and not just for meals, click the menu icon at the top left, select My School and then School Settings.
Click the box next to Show Allergy Icon to enable this feature. (Circled in Red Below)
