Language plan when one parent lives or travels apart

The sources read for this site do not test this arrangement. Nothing in King and Mackey, as the app uses them, and nothing else read studies a child whose parent is away for most of a month, so no honest answer can say what it does to a child's language. What the app can offer is narrower and practical: count the hours across the whole month, plan the away weeks on purpose, and use the home week without trying to make up the whole month in it.

What the sources cover, and what they do not

Two items the app relies on are about hours, not about travel. The first is a father who thought he was doing his part. King and Mackey, as this site's methodology notes describe it, say he had only 3 to 4 hours a week alone with his child, under 5% of the child's waking hours, and that this explained why the child did not speak his language. That is REPORTED: one family's example, with no chapter recorded in the notes. It is not a rate, and it was not about a parent who is away.

The second is a line the app draws at 20% of waking hours. One study, as King and Mackey report it (Pearson and others, 1997), associated about that much exposure with a child being willing to speak a language. That figure is CONTESTED, so read it as a reference point, not a pass mark. Neither item says whether hours that arrive in one concentrated week count the same as hours spread over every week. That is untested here (UNVERIFIED), so what follows is advice about how to plan, not a finding.

Count the month, not one week

ILLUSTRATION, with invented numbers: a 5-year-old. The parent who is away speaks the heritage language and the parent at home speaks the community language. In the home week the away parent spends 20 hours with the child. In each of the other three weeks there are three video calls of 20 minutes, which is 1 hour. The app's working estimate for ages 3 to 5 is 11.5 waking hours a day, or 80.5 a week. That estimate has no cited source (UNVERIFIED).

• The home week alone: 20 of 80.5 hours, about 25%, above the 20% line.
• An away week alone: 1 of 80.5 hours, about 1%.
• The four-week average: (20 + 1 + 1 + 1) ÷ 4 = 5.75 hours a week, about 7%, below the line. At this age the line is 16.1 hours a week, so the average is about 10 hours short of it.

The audit takes one hours-per-week figure for each caregiver, so for this household enter the four-week average. Entering a single week would show 25% or 1%, and neither describes the month. The audit counts what you log, so whether a video call is worth an hour is your decision, and the sources read do not settle it.

Plan the away weeks on purpose

The plan generator takes minutes per day and has no setting for a parent who is away, so decide who carries the language on those days before you generate a plan. ILLUSTRATION from the plan code: the same child, 30 minutes a day, a conversation goal. The plan gives 14 minutes of talk, 7 of reading, 5 of songs and 4 of a family ritual, which totals 30. The app's wording for the ritual names a call as one example of a moment where the language is the default.

1. Decide who speaks the heritage language on away days. If it is the parent who is away, calls and voice messages are the only route. If it is the parent at home, the plan runs as written.
2. Give the family ritual slot a fixed time that already exists, such as bedtime, so nobody has to decide each evening.
3. Use the reading slot for the away parent: read one book by video, and keep it short. If your child asks for the same book again, read it again.
4. Log the calls in the audit as their own entry, apart from in-person hours, so the monthly figure shows where the hours come from.

These four steps are practical suggestions. Neither the app nor the sources read test them.

Use the home week without cramming

In the home week the audit shows a different picture: 25% in the example already clears the 20% line. Keep the plan's daily minutes so your child's routine does not change, and put the extra time into what is easiest in person: meals, getting dressed and walks, which is how the plan describes immersion talk. Do not try to fit three weeks into one. The sources read do not say that works.

What is still unknown

• What a month with one week of a parent's presence does to a child's language. No source read for this site tests it (UNVERIFIED).
• Whether hours in one week count the same as hours spread over the month.
• Whether time on a call counts the same as time in the room.
• Whether the 20% line is a threshold at all. It is CONTESTED.

If you worry about your child's speech or development, that is a question for a professional, such as a pediatrician or a speech-language therapist.
