When a child loses someone, they love, we naturally watch for signs of sadness – tears, quietness, a faraway look. But grief rarely stays where we expect it to. It moves through the whole child, not just their emotions, and often speaks through the body long before it finds words. Sometimes a child’s body communicates what they don’t yet have the language to say.

At Mosaic, we see this pattern often. A child may not be able to tell you they feel frightened or overwhelmed – those are big feelings for a young mind still learning how the world works. Instead, they might say their tummy hurts, that they’re too tired to get up, or they simply can’t sit still. These aren’t distractions from grief. They’re often grief itself, showing up the only way it currently can.

Why can grief affect the body?

Bereavement can be a huge experience for a child to process. Alongside the sadness of losing someone important, there may be changes to routines, worries about other people they love, questions about death or a sense that life suddenly feels less predictable.

Even when a child does not appear visibly upset, their body may still be responding to that stress. Grief can affect:

• Sleep and energy levels
• Appetite and digestion
• Concentration and memory
• how tense or restless the body feels
• How easily a child can relax or settle

There is no single pattern. Some children may experience several of these changes, while others may experience very few.

Tiredness and changes in sleep

Grief can be exhausting. A child may seem more tired than usual, need extra rest or find activities they previously enjoyed harder to manage. School, hobbies and socialising can all take more energy when a child is coping with bereavement.

Sleep can also become more difficult. Some children may struggle to fall asleep, wake during the night, have nightmares or feel anxious about sleeping alone. Others may want more reassurance at bedtime or sleep more than usual.

A calm, predictable bedtime routine can help. Familiar things such as a story, quiet music or simply spending a little extra time together can provide comfort when other parts of life feel uncertain.

Headaches, tummy aches and feeling unwell

Children do not always have the words to describe complex feelings, especially when those feelings are new or overwhelming. Instead of saying, “I feel anxious” or “I miss them”, they may say, “My tummy hurts”, “I have a headache” or simply, “I don’t feel well”.

These physical sensations can be very real. Rather than dismissing them or assuming they are caused by grief, it can help to respond with curiosity.

You might ask:

• “Can you tell me what it feels like?”
• “Where do you feel it in your body?”
• “Is there anything that makes it feel better or worse?”
• “Do you think your body needs rest, food, water, movement or quiet?”

These gentle questions can help children notice links between how they feel physically and emotionally.

Changes in appetite

Grief can affect appetite too. Some children may eat less than usual; lose interest in foods they normally enjoy or say they are not hungry. Others may want to eat more often or seek familiar foods for comfort.

Mealtimes can also feel different after a death, particularly if the person who died was part of the family’s usual routine. Keeping meals and snacks predictable can provide some helpful structure, while gentle encouragement is often more useful than pressure.

Restlessness and difficulty concentrating

Grief does not always look like sadness. Some children become more restless, fidgety, irritable or energetic and may find it difficult to settle. Movement such as walking, running, playing outside or sport may help release tension, while others may prefer quieter activities such as drawing, reading or listening to music.

A grieving child may also find it harder to concentrate, remember information or complete everyday tasks. They may forget instructions, lose things more often or struggle with schoolwork. This can sometimes look like a lack of effort, when in reality their mind may be working hard to process what has happened.

Small adjustments can help, such as:

• Breaking tasks into smaller steps
• Offering reminders
• Allowing more rest and downtime
• Reducing pressure when a child feels overwhelmed
• Giving them opportunities for movement and fresh air

Grief might look like…

Sometimes adults notice the physical symptom before they notice the emotion underneath it. A child might say:

• “I’m tired.”
• “My tummy hurts.”
• “I can’t sleep.”
• “I’m not hungry.”
• “I can’t concentrate.”

These words can have many possible causes. Tiredness may come from poor sleep or emotional exhaustion, while a tummy ache might appear alongside anxiety or worry. The important thing is not to jump to conclusions, but to stay curious about what else may be going on.

Every child experiences grief differently

There is no checklist that a grieving child should fit. Some children may talk openly about the person who died, while others may express themselves through play, behaviour, physical symptoms or changes in routine.

Their responses may also change over time as their understanding of death develops. What matters most is making space for questions, feelings and support as and when they need it.

When to seek further help

Physical symptoms should never automatically be put down to grief. If symptoms are severe, persistent, getting worse or causing concern, it is important to speak to an appropriate healthcare professional.

This is especially important if a child is struggling significantly with eating, sleeping, school or everyday life. Seeking advice helps make sure that other possible causes are considered.

How Mosaic can help

Mosaic offers free support to bereaved children, young people and their families across Dorset. Children do not need to be able to explain exactly how they feel before they can benefit from support.

Support includes:

• One-to-one specialist counselling for children and young people.
• Advice for parents and teachers at any point following a death.
• Activity days and social opportunities where families can come together, meet others and enjoy time together.
• Bereavement Cafés, giving young people a compassionate space to meet others and use creative activities to help process their grief.

Sometimes grief is spoken and sometimes it shows up through the body. Recognising those signs can help adults respond with patience, reassurance and the right support when a child needs it most.
