Why this is hard to keep track of

  • Generic sleep hygiene advice assumes a cause that frequently isn't the cause
  • The night is shaped by the day, and sleep trackers only ever look at the night
  • Night waking is what you remember; how long settling took is what predicts tomorrow
  • Melatonin decisions get made on impressions because there's no before-and-after

Worth recording

  • How long settling actually took, from in bed to asleep
  • Night waking, and roughly how long each one lasted
  • What the day contained — sensory load, changes to plan, exercise, screens
  • How the following day went

Cadence

Two lines at night, one in the morning

In practice

Say it once, in whatever words you have

The moments most worth recording are the ones where filling in a form is the least realistic thing in the world. A sentence, typed or dictated afterwards, is a much lower bar — and it carries the context a checkbox would have lost.

Sleep Chat

Took two hours to settle again. Busy day — soft play in the afternoon and then Grandma turned up unannounced.

Called 4 tools

  • log_sleep(settle_min: 120, night_wakes: 1)
  • log_day_load(["soft play", "unplanned visitor"])
  • find_pattern(metric: "settle_time", group_by: "day_load")
  • compare_periods(metric: "settle_time", window: "term")

Logged. Settling has gone over 90 minutes on eleven nights this term, and nine of those followed a day with an unplanned change in it. Soft play on its own averages 45 minutes.

Every figure here was counted from entries you made. The model picked which tools to call — it doesn't interpret, diagnose, or decide what anything means about anyone.

And then ask

The question the log can answer

Months of entries hold real answers to the questions you've been guessing at, and reading them properly has always meant a spreadsheet and a free evening — which is not a thing anyone in this situation has.

Ask in plain language. The answers come back with the numbers behind them, including when those numbers are too thin to mean anything yet — which is the more useful answer more often than people expect.

Asking about the pattern Chat

Is it the screens?

Called 3 tools

  • get_history(topic: "sleep", window: "6m")
  • find_pattern(group_by: "antecedent")
  • compare_periods(metric: "events")

Doesn't look like it. Screen evenings average 52 minutes to settle and non-screen evenings 48, which is inside the noise. Days containing an unplanned change average 94. That's the one worth acting on.

Counts and averages over your own entries, nothing more. Where the data is confounded or too thin, the answer says so instead of rounding it into a conclusion.

The reason most people start

Something to actually bring to the appointment

You get fifteen minutes, once, after waiting months for it. The questions are specific and the honest answers are all some version of "I don't know, it's hard to say".

What this gives you: Weeks of settling times and night wakings with the days attached, which is what a paediatrician needs and what nobody ever arrives with.

  • Export the date range you were asked about, as a file you can print
  • Counts and timings rather than an impression of the worst week
  • Your own notes kept alongside the numbers, in your words
  • Nothing shared anywhere unless you choose to share it

What it won't do

  • Diagnose anything, or suggest that it could
  • Score a person, or rank them against anyone else
  • Set a target for fewer events, or a streak of good days
  • Recommend a treatment, a therapy, a diet or a medication change
  • Share your record with a school, a clinician or anyone else on its own

It's a notebook that can do arithmetic and answer questions about itself. Deciding what any of it means is a job for you and the people advising you.
