Track an allergen introduction window

Allergen schedule

# Track an allergen introduction window

Start a 14-day window for each allergen you introduce, then mark it cleared or mark a reaction.

2 allergens free, Premium for all
You can track 2 allergens on the free plan. Premium tracks every allergen on your list.

## Steps

1. Open the Schedule tab. The first time, read "How the Schedule works" and tap "Got it".
2. Tap the allergen you are introducing.
3. Tap "Mark introduced". A 14-day window starts today.
4. Keep logging meals as usual. Meals with that allergen show under "Logged feeds".
5. When the window ends, tap "Mark cleared" if your baby tolerated it. If there was a reaction, tap "Mark reaction" at any point.

Marking an allergen cleared or as a reaction can't be undone, so check before you confirm.

## Good to know

How windows start, and what the reminders do.

1. With "Allergen window reminders" on in Settings, you get a reminder at 9 am on days 1, 3, 7 and 14 of a window you started with "Mark introduced".
2. Logging a food that contains an allergen also starts its window. Windows started this way don't send reminders.
3. Tap "Add custom allergen" to track a food that isn't on your list.
4. The app records what you introduce. It doesn't tell you when or in what order to introduce allergens.
