By the numbers

What research says about foster carers’ own children.

17studies from the UK, U.S., Canada, Sweden, Belgium and Spain were pulled together in an Oxford review of how fostering affects carers’ own children (2013).
76%of 366 foster carers in one study said their own children felt positive about fostering.
73%of carers in another study rated their children’s reaction to fostering as positive.
24%of the 366 carers said they sometimes neglected their own children because of fostering demands.

The whole family fosters

Your children are part of fostering, not bystanders.

When a family starts fostering, family life changes for everyone. An international review found that carers’ own children were often overlooked by research and by professionals. Being involved in the decision to foster helped children adapt afterwards.

🗣️ Talk before you startInclude your children in the decision, in a way that suits their age.
Read more

Children said they needed to understand how fostering would affect them, both the good parts and the hard parts. Hold a family meeting and let them ask anything.

What to say

  • “We’re thinking about fostering. What do you think?”
  • “Some things will change. Let’s talk about what worries you.”
  • “Your feelings matter to us, before and after.”

What not to say

  • “We’ve already decided, so you’ll have to get used to it.”
  • “You should be grateful you have a family.”
🌻 Many children see the goodMost carers say their children feel positive about fostering.

In two studies, around three in four foster carers said their children reacted positively to fostering. Positive and hard feelings often live side by side.

🧸 Age makes a differenceA toddler, a ten-year-old and a teen will each need different things.
Read more

Younger children may need simple, concrete explanations and more reassurance. Teens may want a bigger say, more privacy and to be treated as part of the team, without being made responsible.

🔁 Keep checking inA yes at the start isn’t a yes forever.
Read more

Information and conversation matter throughout fostering, not only at the beginning. Check in with your children before each new placement and regularly while a child lives with you.

Preparing your children before each placement

The right amount of information helps children cope.

Children who were told about each foster child before they arrived found it easier to understand difficult behaviour, and felt involved. Those who got relevant information got along much better with foster children.

🔒 Share what helps, not every detailSome information is private, and some is too heavy for a child.
Read more

Some children, especially younger ones, didn’t want much information. Learning about a foster child’s past abuse or neglect could be very hard for them to process.

Usually helpful to share

  • How long they might stay (if known)
  • Name, age and what they like
  • Things that might upset them, in simple terms
  • Where they will sleep and what will change

Usually best kept private

  • Details of abuse or neglect
  • The child’s case or court information
  • Information about the child’s parents
🎬 Practise what to expectTalk through the first evening together.
Read more

Explain that the new child may be quiet, upset or very busy, and that it is not about your children. Agree on small ways they can welcome the child, like showing them the toy box.

What to say

  • “He might not want to play at first. That’s okay. He’s had a big day.”
  • “If anything feels strange or worrying, come and tell me.”
🧺 Things your child keeps for themselvesDecide together what won’t be shared.
Read more

Let your child choose a few special belongings to keep in their own space. It is easier to be generous when you know your treasures are safe.

Use the “Family meeting before a placement” worksheet in this guide.

Jealousy and sharing parents

Protected time helps every child feel they matter.

In many studies, carers’ children said their parents became so busy with fostering that they had too little time to listen. Some felt left out or forgotten, even though they understood why the foster child needed attention.

⏰ Protected timeRegular time just for your own child, that fostering doesn’t interrupt.
Read more

Researchers recommend that foster carers set aside time only for their own children, sometimes with the help of respite care for the foster child.

Small ideas

  • A bedtime chat that’s always theirs
  • A monthly outing with one parent
  • Driving them to an activity, phone away
  • Saturday breakfast together
👀 Foster children notice tooA foster child may feel your own children are treated differently.
Read more

Fostered children sometimes feel carers’ children get special treatment, so balancing time needs care. Give every child some one-on-one time, in ways that fit each child.

💬 Naming the feelingJealousy is easier to handle when it can be said out loud.
Read more

What to say

  • “It makes sense if you miss having me to yourself.”
  • “You can tell me when it feels unfair. I won’t be cross.”

What not to say

  • “Don’t be selfish, she’s had a hard life.”
  • “You should be glad you’re not in her shoes.”
The Sibling jealousy in kids guide has more on fairness and one-on-one time.

Sharing space, belongings and privacy

Less room and more people can be hard for everyone.

Carers’ children named sharing belongings, having less personal space and coping with difficult behaviour as some of the hardest parts of fostering. Some really resented these changes, though many found ways to cope.

🏕️ A space of their ownEvery child needs somewhere to retreat.
Read more

Even in a small home, each child can have a corner, a shelf or a box that is only theirs. Agency and state rules may decide who can share a bedroom, so ask your caseworker.

🔁 Rules for borrowingClear rules stop many arguments before they start.
Read more

Ideas

  • Ask before borrowing, every time
  • Give each child a box or drawer that others don’t touch
  • Keep a few “family” toys and games for everyone
  • Replace or repair things that get broken, together
🧩 When something is taken or brokenRespond calmly, and remember where the behaviour may come from.
Read more

A child who has gone without may take or hide things. Handle it privately and kindly with the foster child, and acknowledge your own child’s upset too.

What to say to your child

  • “I’m sorry your game got broken. That’s really frustrating.”
  • “I’ll handle it with him. Let’s find somewhere safe for your things.”

Safety and privacy rules for everyone

House guidelines that protect every child at home.

Child welfare guidance encourages foster and adoptive families to set family guidelines for safety and privacy. They help children who have been hurt feel comfortable, and they apply to every child in the house.

Guidelines many families use

  • Ask before hugging, and respect each person’s comfort with touch
  • Be careful with tickling and play fighting
  • Keep adult intimacy private
  • Knock before entering bedrooms and bathrooms
  • Teach every child about healthy, age-appropriate boundaries
🤫 No secrets ruleChildren should always be able to tell an adult if something feels wrong.
Read more

Teach the difference between surprises (which are happy and get told soon) and secrets (which feel uncomfortable). Make sure your own children know they will never be in trouble for telling you something worrying.

What to say

  • “If anyone ever makes you feel uncomfortable, even another kid, you can always tell me.”
👁️ Supervision when neededSome children need extra supervision with other children.
Read more

If a child has a history of sexual abuse or concerning behaviour, guidance says to supervise their play with siblings and other children. Some children cannot be left alone with younger children at all. A family safety plan, made with your caseworker, can help.

🙅 Your children aren’t the caregiversDon’t ask your children to watch, report on or babysit foster children.
Read more

Some carers’ children didn’t want to be too involved, because being involved also meant responsibility. Children with behaviour concerns should not be given authority over other children either.

If you see behaviour that worries you between any children, step in calmly, keep everyone safe, and tell your caseworker the same day.

What can your children tell friends?

Helping children keep a foster child’s story private.

Carers’ children said they felt they couldn’t tell friends why their foster brother or sister acted in a certain way. Keeping someone else’s story private can feel lonely, so give your children words they can use.

🗨️ Simple, private answersA short script makes awkward questions easier.
Read more

What your child can say

  • “She’s living with us for a while.”
  • “That’s his private story, so I don’t share it.”
  • “He’s part of our family right now.”

What not to share

  • Anything about the child’s parents
  • Photos of the foster child online
  • Why the child is in care
🏡 Somewhere safe to talkYour child still needs someone to talk to.
Read more

Let your child know they can always talk to you, your partner or your agency worker about what happens at home. Some agencies run groups for sons and daughters of foster carers, which children in research said were a good way to get information.

Helping them get along

Connection grows slowly. It can’t be forced.

Each foster child and each carer’s child is an individual, and their personalities shape how they get on. Some become close, some just share a home politely, and that’s okay.

🎲 Shared fun, low pressureDoing things side by side is easier than talking face to face.
Read more

Ideas

  • Baking or cooking together
  • Board games with clear rules
  • Building, crafts or Lego
  • Family walks, bike rides or a park trip
  • Movie night with snacks they chose
🌱 Don’t force closenessAvoid “Be nice, she’s your sister now.”
Read more

What to say

  • “You don’t have to be best friends. Just be kind.”
  • “Would you show him where the games are?”

What not to say

  • “You have to share everything with her.”
  • “Why can’t you be more like him?”
⚡ When they fightStep in early and teach repair.
Read more

Stay calm, separate if needed, and hear each child privately. Avoid automatically blaming either the foster child or your own child.

The When siblings hit, fight & compete guide has steps for repair and problem-solving.

Listening to your birth children

Give them permission to complain, and really hear it.

Children coped better when they could openly talk about problems with their parents and could show negative feelings about fostering without being judged. Some said they hid their own problems so they wouldn’t trouble their parents, or felt they weren’t allowed to complain.

🎙️ Permission to complainHard feelings about fostering are allowed.
Read more

What to say

  • “You’re allowed to find this hard. Tell me the worst bit.”
  • “You can be annoyed with fostering and still be a kind person.”

What not to say

  • “I don’t want to hear complaints.”
  • “You have no idea how lucky you are.”
🚩 Signs your child is strugglingChildren don’t always say it in words.
Read more

Things to notice

  • Changes in sleep, appetite or schoolwork
  • Clinginess, or pulling away from you
  • More time alone in their room
  • Saying “I’m fine” a lot while seeming upset
  • Worries about safety or their belongings

If changes last more than a few weeks, talk with your child’s clinical provider, school counselor or your agency worker.

📆 A regular check-inA predictable time to talk makes it easier to speak up.
Read more

Some families use a weekly “How are things really?” chat, or a notebook your child can write in and leave for you. Agency workers can also give children a chance to share their views.

Your child can use the “My check-in” worksheet in this guide.

When a foster child leaves: your children’s goodbyes

Your children may grieve too.

Some carers’ children said endings were the hardest part of fostering. In several studies, children weren’t told when a foster child was moving, and their grief and loss weren’t recognised.

🗓️ Tell them early and honestlyGive your children time to prepare and say goodbye.
Read more

What to say

  • “Jayden is going to live with his grandma next week. How do you feel about that?”
  • “It’s okay to feel sad and happy at the same time.”

What not to say

  • “It’s no big deal, there’ll be another one.”
  • Nothing at all, hoping they won’t notice
🎈 Ways to say goodbyeSmall rituals help children close the chapter.
Read more

Ideas

  • A drawing, card or letter for the foster child
  • A goodbye meal or small party
  • A photo of the children together (if allowed)
  • Talking about favourite memories
The When a foster child leaves: goodbyes, grief & reunification guide covers goodbyes for the whole family.
