Helping a Foster Child Manage Anxiety: What Actually Helps

Anxiety rarely arrives announced. It turns up as a stomach ache on a Tuesday morning, a child who cannot get out of the car outside school, or a nine-year-old who needs the landing light on at an age when nobody expects it. If you have seen something like that in your home and you are not sure whether it is ordinary nerves or something that needs a GP, this article is for you.

Please note: this is general information for foster carers, not medical advice about a particular child. Figures quoted are correct at August 2026. If you are worried about a child’s health, speak to their GP and to your supervising social worker. The NHS guidance for parents and carers is at nhs.uk.

What anxiety actually looks like

Children very rarely say “I feel anxious”. They show it instead, and often in ways that get read as bad behaviour. A child who refuses to go into a birthday party looks rude. A teenager who spends four hours behind a closed door looks difficult. Both may be doing the only thing that feels safe.

The signs tend to cluster in three places:

• In the body: stomach aches and cramps, nausea, a racing heart, sweaty palms, chest pain, trouble getting to sleep, a change in appetite.
• In behaviour: nightmares, tearfulness, irritability, avoiding particular people or places, clinginess in younger children, hair pulling or skin picking, refusing to leave a room or the house.
• In how they think: constant worrying, feeling panicked or overwhelmed, struggling to concentrate, going over the same fear again and again.

The NHS splits these roughly by age. Younger children get irritable, tearful and clingy, have trouble sleeping and may start wetting the bed again. Older children lose the confidence to try new things, find it hard to concentrate, have angry outbursts and pull back from friends and school.

No single sign proves anything. A stomach ache is usually a stomach ache. What matters is the pattern: several together, lasting weeks, showing up before the same trigger every time.

Why it is so common for children in care

Because it is. Of the children in care in England on 31 March 2025 who had a Strengths and Difficulties Questionnaire completed, 42 per cent scored in the range treated as a cause for concern, and the average score was 14.9. Across all children aged 8 to 16 in England, 20.3 per cent had a probable mental health condition in 2023. Children in care sit well above that.

That is not a mystery. A child who has lost a home, a school, a bedroom and a set of familiar smells has learned that things disappear without warning. Their nervous system draws the obvious conclusion and stays braced. This is the same ground covered by trauma and attachment, and how a child’s early experiences shape their response to ordinary events. Anxiety in a child who has moved several times is often not irrational. It is an accurate memory doing its job at the wrong moment.

Which is why “there’s nothing to worry about” lands so badly. To the child, there has been plenty to worry about, and you have just proved you do not get it.

What helps when anxiety spikes

A panic attack usually peaks and passes within about five to twenty minutes, though it feels far longer to the child living it. Their heart hammers, they cannot get a full breath, and they may feel oddly detached from their own body. It is frightening to watch. Your job in those minutes is only to be steady while it passes.

A few things that work:

• Slow the out-breath. In for a count of three, out for a count of seven. The long exhale is what settles the body, so make the out-breath the part you stress.
• Move somewhere quieter and let them lie down, a hand on their stomach so they can feel the breath moving.
• Use the senses to bring them back to the room: five things they can see, four they can hear, three they can smell, two they can touch, one they can taste.
• Say plainly that it will pass and their heart will slow down, and repeat it calmly. Headphones and familiar music help once the worst has gone. You are lending them your nervous system until theirs comes back online.

What you do not do is reason with them mid-attack or promise it will never happen again. Connection first, conversation later. That is the idea behind therapeutic parenting with PACE, and a panic attack is where it earns its keep.

What helps over weeks and months

The daily stuff matters more than any single conversation. Anxiety shrinks when a child’s world becomes predictable and their body is looked after.

• Say out loud what is happening tomorrow, and mean it. If Thursday’s swimming is cancelled, tell them on Wednesday. Small broken promises are expensive in a house where a child is already braced for change.
• Name anxiety for what it is. The racing heart and the churning stomach are the body’s alarm going off: uncomfortable, not dangerous, and something everyone’s body does.
• Watch caffeine and sugar, particularly late in the day. Energy drinks and a 3am wake-up are close relatives.
• Protect sleep. A consistent bedtime, a wind-down without a screen, a light left on if that is what it takes.
• Get outdoors. A walk, or a kickabout in the park. Anxious bodies hold a lot of unused adrenaline and it has to go somewhere.
• Make a self-soothe box together. A shoebox of things they like to look at, hold, smell, taste or listen to: a photo, a smooth stone, a particular hoodie, a playlist. Making it on a calm day is half the point, because it gives them something to reach for on a bad one.

Watch too for coping strategies that work for an hour and cost a lot later: alcohol, cannabis, or hurting themselves. If you see that, do not panic and do not lecture. Tell your supervising social worker the same day, and be honest with the young person about why those routes make the next week worse.

School deserves its own mention. Anxiety shows up loudest at the school gate, and the Personal Education Plan is where to get arrangements written down: a named adult to check in with, permission to leave the classroom, a quiet spot at break. Carers who talk to school early get further than those who wait for the third phone call home.

When to ask for more help

Ask when the anxiety is severe, when it has lasted weeks rather than days, or when it is getting in the way of ordinary life: school, sleep, eating, seeing friends. That is the NHS threshold and it is a sensible one. Start with the GP and tell your supervising social worker at the same time. Anxiety is one part of a bigger picture, so read this alongside supporting a child’s mental health.

A few things worth knowing before you go:

• There is no blood test for anxiety. A GP may run tests to rule other things out, which is not the same as being fobbed off.
• A child may not get a diagnosis at all. Anxiety tied to a specific stretch, exams say, or a court date, often eases once the stress lifts.
• Every child in care has a health plan, with a review health assessment twice a year while they are under five and once a year from five upwards. That review is a good place to raise a worry you have been sitting on.
• If talking things through is offered, getting them there matters. Appointments missed twice tend to become appointments cancelled.
• YoungMinds runs a free Parents Helpline on 0808 802 5544, open 9.30am to 4pm on Monday, Thursday, Friday, and until 6pm on Tuesday and Wednesday, with a webchat available too. Childline is free on 0800 1111 and Samaritans are on 116 123 around the clock. Kooth offers free online counselling for young people, though it is commissioned area by area, so check whether it covers your borough.

You won’t have to do this alone

Supporting an anxious child is tiring in a way that is hard to explain to people who have not done it. The vigilance is catching. You start scanning the room too.

That is the point of the support around you. Your supervising social worker is on the end of the phone between visits, and there is a 24-hour out-of-hours line for the evening when a child cannot stop shaking and you want a second opinion. Training covers this ground, and other GLF carers who have sat through the same 2am panic attack are often the most useful people you will speak to. Greater London Fostering was inspected by Ofsted in July 2025 and rated Outstanding in all three judgements, and the support carers get is a large part of why. Carers are paid a fixed weekly fee, currently 479.50 pounds for a child under 11 and 507.50 pounds for a child aged 11 or over, so the money side stays steady while you concentrate on the child.

You do not need a psychology degree for this. You need to be the adult who stays calm, keeps Thursday the way you said Thursday would be, and does not flinch when a child tells you what frightens them.

Frequently asked questions

Do I need any qualifications to support a child with anxiety?

No. GLF’s training covers anxiety and how children respond to stress, and your supervising social worker will talk any situation through with you. What matters far more is being consistent and calm.

How do I tell the difference between anxiety and a child playing up?

Look for the pattern rather than the single incident. Anxiety attaches to a particular trigger, comes with physical signs like stomach aches, and gets worse when the child is pushed. If you are unsure, write down what you see for a fortnight and show your supervising social worker.

Should I make a child face the thing they are frightened of?

Not head-on and not alone. Avoidance does make anxiety grow, but the way through is small planned steps with you alongside, agreed with the child in advance. Forcing it sets things back.

Can I foster if I have never dealt with a child’s anxiety before?

Yes. Most carers have not before they start. You will be trained, matched carefully and supported, and nobody expects answers on day one.
