When foster children and your own children live together
The whole family fosters. Every child in your home deserves to feel safe, heard and loved.
By the numbers
What research says about foster carers’ own children.
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.

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.”
Read more
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.

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