Ask about the parts of the day with other people in them: the corridor between lessons, the dining hall, being called on, changing for sport, walking in late while everyone looks up. Those answers tend to come out quietly, and they will not come out at all if the child thinks you have already decided they are being difficult.

Distress you can soothe, and then move through together. A worked out case, less demanding work, nobody staring, no awkwardness at lunch, is something they will defend, and you can find yourself arguing rather than helping. Treat it as information when you hear it: the avoiding has settled in, and the return will need negotiating and not only comforting.

The child looking after an unwell parent, the teenager who has written the school off, and the one who cannot face the corridor all look the same on the register. They need three different responses, and a ladder of graded steps aimed at the wrong one can waste months. Ask what a morning they do not go actually looks like, and what would have to change for that morning to go differently.

Writing down which of those happened each day gives you something to watch. Most of the real movement, in both directions, happens inside days that would go down as present, and an attendance register hides all of it. A child who used to leave at eleven and now stays until two has had a good week, and should be told so.

Patterns drift. A child frightened of the dining hall in September can, by March, be a young person with a settled day at home and a set of arguments ready to defend it, and looking only at March means treating the wrong thing. The early story usually still matters, and saying it out loud without accusation often softens a conversation more than any argument about attendance.

Children recognise this straight away when it is put plainly: the lovely feeling when you find out you do not have to go. Adults know it too, in the cancelled meeting and the message left unanswered. Once everyone can name it out loud, nobody has to play the villain in the morning, and you are all looking at the same trap instead of at each other.

This is not a punishment and it should not sound like one. It is about a sum the child does without noticing: if home offers the same day with none of the hard parts, no argument about the future will make school the better option. Say the rule plainly and without heat, hold it, and let the comparison do the work for you.

None of those mean the plan was wrong. They are the ordinary weather of this work, and a family who heard them named in advance treats a bad week as a bad week rather than as proof that nothing works. Sibling knock on is worth planning for from the start in particular, because a rule that applies to only one child in a house rarely survives the month.

When staying home works on one morning in four, that occasional success makes the pleading more determined rather than less. Cut the plan back until it is something two tired adults can manage on a Wednesday: one rule, one reward, one person checking. Add to it later if it holds, and tell whoever is helping you early when it slips, so it can be simplified instead of abandoned.
