Teenagers, toddlers, the other parent and when it's more than shouting

When they're teenagers. Wang and Kenny's study is about thirteen-year-olds, and it's the age at which the shout does the most measurable harm and works the least. Teenagers aren't managed by instruction. They're managed by arrangement, which means fewer instructions, agreed in advance and at calm moments, with consequences you'd actually apply. And more listening than talking, because the fifteen-year-old who tells you things is the one you didn't shout at when they were thirteen.

When they're toddlers. A two-year-old can't do many of the things they're told, and the NHS page is clear that difficult behaviour at that age is usually tiredness, hunger, overexcitement, frustration or boredom. The quiet ask still applies, at their level, in short words. The follow-through is nearly always physical help. And the conditions matter more than anything, because a tired two-year-old can't be reasoned with and isn't being naughty.

When it's siblings fighting. Two children at each other is the flashpoint most likely to produce a shout at both of them, which teaches both that shouting is how conflict ends. Separate them, calmly, without a verdict on who started it. Consequences for both if you can't tell, delivered flat. Then leave it.

When the other parent shouts. You can't do the method for two, and a house with one quiet asker and one shouter is confusing for a child. Talk to your partner at a calm moment, about the ladder, not about their character. Show them the chapter 1 list. Agree the three flashpoints and the small consequences together. If they won't, do your part anyway. One reliable parent is better than none.

When grandparents or others undermine it. They'll do it their way. That's all right. Children learn that different adults have different arrangements, and what matters is that yours is consistent.

When it happens in public. The shout in the supermarket is the one you feel worst about, because of the audience. The method is the same. Go to the child, get down, one instruction, low voice. The audience is far more impressed by a quiet parent than an angry one, and if they're not, they're not your concern.

When you hit, or fear you might. The first caution in this book. If it's happened, or if the shout is starting to have a hand in it, please talk to someone this week. Your health visitor, your GP, or the Family Lives helpline on 0808 800 2222. This isn't a matter for a book.

When the house is frightened of you. If your partner is afraid of your temper, or you've been told you're frightening, that's beyond shouting at children and it needs help. The National Domestic Abuse Helpline on 0808 2000 247 is for anyone in a household where someone is afraid.

When you're the one who's struggling. Exhaustion, low mood, a marriage under strain, money, a job that's eating you. All of these arrive at ten past six as a shout. If you've felt low most of the day for a couple of weeks, or the shouting is new and out of character, see a GP. The shout may be the symptom.

When you'd like help with all of it. Parenting programmes exist, and they work. A Cochrane review of thirteen trials found that group-based parenting programmes reduced children's conduct problems, improved parents' mental health, and reduced harsh parenting, at modest cost. Ask your health visitor, your GP or your child's school what's available locally. There's no shame in it. It's what the evidence recommends.

When you slip. You will. Do the repair, that day, and go back to the quiet ask on Thursday. One shout doesn't rebuild the ladder. Not repairing it does.
