Understanding reminders

Reminders are lindly’s safety net — an occasional, gentle “it’s been a while — all good?” rather than a stream of alarms. This guide explains how they work and how to make them yours.

lindly is not a medical device and doesn’t diagnose anything. Reminders are prompts to glance, never verdicts. If you’re worried about your baby, contact your pediatrician or midwife.

1. Know the three rules

lindly watches three time gaps:

• No wet diaper — a long stretch with no wet diaper logged.
• No feed — a long stretch with no feed logged.
• No sleep — your baby has been awake longer than expected.

Each is a calm check-in, phrased as a question and dismissible in a tap.

2. Understand how a reminder fires

The engine watches the gap since the last logged event of that kind, and every threshold scales with your baby’s age — a newborn and a toddler get different numbers, because their normal rhythms are different. We chose those defaults from published pediatric guidance and deliberately set them to fire late rather than early, so ordinary variation doesn’t trip them. We wrote up that evidence in detail on the blog: how we set our reminder defaults.

One nice consequence: because the rules only care about too-long gaps, more frequent feeding or an extra nap can never cause an alarm.

3. Learn what quiet hours do

Overnight, most reminders are held until morning rather than pinging you at 3 a.m. The one exception is no wet diaper, which we treat as the signal worth surfacing even overnight — but its thresholds are set with enough headroom that a normal night, where an older baby sleeps long and simply isn’t changed, won’t fire a false alarm at dawn.

4. Dismiss a reminder

When a reminder appears, tap All good to dismiss it. Dismissed reminders don’t immediately re-fire for the same gap, and they stay visible but subdued on the Reminders tab, so you have a record of what came up.

5. Adjust thresholds per child

Every default is exactly that — a default. You know your baby better than a table does, so each threshold is adjustable per child in the reminder settings. If a rule fires a little too eagerly or not quite soon enough for your little one, tune it. The no sleep rule in particular is the gentlest of the three by design, since wake windows are about comfort rather than safety.

That’s the whole system: quiet by default, honest about its limits, and yours to adjust.
