When one child is upset about Mum or Dad leaving, the loudest feelings can quickly take over the household. Yet military sibling support matters just as much for the child who goes quiet, becomes extra helpful, acts silly at bedtime, or insists they are “fine”. Defence life changes the rhythm of the whole family, and each child will experience that change in their own way.
For Australian Defence Force families, a posting, exercise, deployment or extended training period can bring pride alongside sadness, worry and frustration. Siblings share the same home and the same absent parent, but they do not share the same temperament, age or understanding. Supporting them well is not about making every feeling disappear. It is about helping each child feel noticed, safe and unconditionally loved.
Why siblings can have such different reactions
Children often compare their reactions to a parent’s time away. An older child may understand the reason for a deployment but feel annoyed at the extra jobs at home. A younger child may not grasp the length of the separation, yet become clingy or unsettled by a changed bedtime routine. Another child may appear unaffected at first, then burst into tears over something small weeks later.
None of these responses means a child is coping badly. They are ways of communicating that life feels different.
Sibling dynamics can add another layer. One child may receive more attention because they are visibly distressed, unwell, or finding school difficult. The other may decide they should not add to the pressure. They might become the “easy one”, putting aside their own worries to protect the parent who is at home. While their kindness can be genuine, children should not feel responsible for holding the family together.
This is why it helps to avoid labels such as “the brave one”, “the sensitive one” or “Mum’s little helper”. Labels can quietly lock children into a role. Instead, make room for the idea that feelings can change from one day to the next.
Military sibling support starts with being specific
A broad question such as “Are you okay?” can be hard for a young child to answer, especially when they do not yet have the words for what is wrong. Gentle, specific observations give them somewhere to begin.
You might say, “You seemed cross when we packed Dad’s bag. I wonder if part of you wishes he did not have to go.” Or, “Your brother has been missing Mum loudly today. Sometimes quieter feelings need space too. How has today been for you?”
This approach does not put words in a child’s mouth. It lets them know you have noticed, and that no answer is required straight away. A shrug, a change of subject or “I don’t know” can be the beginning of a conversation rather than the end of one.
Try to speak with each child one-to-one where possible. Ten calm minutes in the car after school, while folding washing, or at bedtime can be more useful than arranging a big family talk. For children who find direct conversation uncomfortable, drawing, building with blocks, reading together or kicking a ball can make sharing feel less intense.
Keep routines steady, but make room for feelings
Predictable routines are reassuring during a parent’s absence. Knowing who does school drop-off, what happens after dinner, and when a video call may be possible gives children a sense of structure when other things are out of their control.
That said, routine should not become a reason to rush past emotion. A child who is suddenly refusing to go to swimming, arguing with a sibling or struggling at lights-out may be asking for connection, not simply testing limits. Boundaries still matter, but connection makes those boundaries easier to hold.
You can say, “It is okay to be angry that Mum is away. It is not okay to hurt your sister. Let’s work out what your angry body needs right now.” This separates the feeling from the behaviour. Children learn that every emotion is welcome, while not every action is safe or fair.
It can also help to build small moments of choice into the week. Let siblings choose the Friday movie, take turns picking a meal, or decide where to display a drawing for their away parent. These choices will not change the separation, but they remind children that their voice still matters at home.
Help siblings stay connected without making it a job
Children often enjoy sharing a connection ritual with their away parent. It might be a voice message before bed, a photo of something ordinary from the day, a shared book read over several calls, or a paper chain that marks the passing weeks. Keep it simple enough that it does not become another task for the parent at home.
For siblings, individual connection matters too. If every call is shared, the more talkative child may take over while the quieter child disappears into the background. When time zones, work demands and service conditions allow, short individual messages can help each child feel remembered. A recorded “good luck at your assembly” or “I loved hearing about your dinosaur drawing” can mean a great deal.
There will also be times when contact is unpredictable or unavailable. It is kinder not to promise a call that may not happen. Instead, use language children can trust: “We are hoping to hear from Mum this weekend. If we cannot, it will be because of her work, not because she has forgotten us.”
A connection box can be useful during those gaps. Include letters, printed photos, a familiar item, drawings to post later, and a notebook where children can record questions or stories. It gives feelings somewhere to go when contact cannot happen on demand.
Avoid asking one child to carry too much
Older siblings can take on more responsibility during a busy period, and many are proud to contribute. Helping pack lunches once in a while or reading to a younger sibling can build confidence and connection. The trade-off is that help can become pressure when it is expected, praised as maturity, or treated as a substitute for adult support.
Be clear that older children are still children. They should be able to play, see friends, complain about their own day and say no to helping sometimes. Thank them for what they do without suggesting the family depends on them to cope.
It is equally worth watching for younger siblings who are expected to understand less, wait longer or “not make a fuss”. Being little does not make a child’s feelings smaller. Give each child age-appropriate information and a chance to be heard in their own right.
Make homecoming a family adjustment, not a finish line
Homecoming is often imagined as the happy ending, but it can be a readjustment for everyone. Children may be delighted, shy, clingy, cranky or unsure of the returning parent’s place in everyday routines. Siblings might compete for attention after having learnt to manage without it.
Lowering the pressure for a picture-perfect reunion helps. Keep early days gentle where possible. Let the returning parent rejoin ordinary routines slowly, and give children permission to take their time. A child who hangs back is not rejecting their parent. They may simply be working out how life fits together again.
One-to-one time can be particularly helpful after a return. It does not need to be costly or elaborate: a walk to the park, a board game after dinner, or helping make breakfast together can rebuild familiarity. Try not to compare children’s reactions. Each relationship will find its own way back.
When extra support could help
Most children have wobbly moments around separation and change. However, it may be helpful to speak with a GP, school wellbeing staff member or qualified child and family professional if a child’s distress is persistent, escalating, or significantly affecting sleep, friendships, school attendance or daily life.
Let trusted adults know what is happening at home. A teacher who understands that a parent is away can respond with more patience if a child seems distracted, tearful or unusually withdrawn. You do not need to share every detail for a child to receive understanding.
Stories can also create a gentle opening for hard conversations. Reading about children facing a separation can help siblings recognise that their thoughts are not strange or wrong, and can give parents natural words to use when their own are hard to find. Resources made with care for defence-connected children can be a practical part of that support.
Children do not need perfect adults or perfect goodbyes to feel secure. They need truthful reassurance, room for every feeling, and repeated proof that they matter just as much as anyone else in the family. When siblings are seen individually, they can face the changes of service life side by side without having to carry them alone.
