Talking to preschoolers (3 to 5) about separation

Preschoolers ask big questions in small moments: in the bath, at the supermarket, as you turn out the light. "Is Daddy coming back?" "Did I make Mommy sad?" You do not need long answers. You need short, true ones you can say the same way every time.

This guide explains how 3 to 5 year olds make sense of a separation, what to say and avoid, what their behaviour is telling you, and when to ask for help. For planning the first conversation itself, see how to tell your children you are separating.

A note on safety. If there has been family violence, or you are afraid of the other parent, telling your child together or sharing handovers may not be safe. Read separation and safety planning first. Press Shift+Esc to leave this site quickly.

How preschoolers see it

Justice Canada's guidance on children aged 3 to 5 describes the main things to understand about this age:

• They may think it is their fault. Preschoolers may believe the separation happened because of something they did, or that a parent is leaving them.
• They can mix up real and imaginary. A fear can feel like a fact.
• They do not understand the words. Preschoolers "won't understand terms like separation or divorce." What they can understand is homes, beds, days and people.
• They need it in pieces. Give them "some facts at the beginning, with more information given over time."

A 2016 review of international research for the UK government, by the Early Intervention Foundation, found that pre-schoolers are "more likely to ascribe self-blame, threat, and fear of conflict" than older children, and that "Children who blame themselves for parental disagreements or feel responsible for not helping to end them experience guilt, shame, and sadness/depression." That is why the "not your fault" message matters so much at this age, and why it needs saying many times, not once.

What to say

Keep each message to one or two sentences. Use names and places, not concepts.

The first explanation

These examples say "Mommy" and "Daddy". Use whatever names your child uses for each of you: Mama and Mom, Papa and Dad, or something else entirely.

When they ask if it is their fault (even if they do not ask)

Preschoolers often will not ask this out loud. Say it anyway, and say it again at bedtime, in the car, and when you see them being extra good or extra quiet.

When they are afraid you will leave too

When they ask when the other parent is coming back

When they say "I want you to live together again"

Justice Canada's rule applies here: "If a statement on this list isn't true in your case, don't say it." A small child will hold on to "maybe".

Making two homes make sense

• A picture calendar. Preschoolers cannot read dates, but they can follow pictures. Use a simple week with a symbol or colour for each home and let your child move a marker each morning. Keep a copy in both homes if you can.
• A comfort object that travels. The Ontario chapter of the Association of Family and Conciliation Courts (AFCC-Ontario) notes that transitional objects, such as a favourite toy or blanket, moving between homes help preschoolers. Its guide also says children's personal possessions should go with them "regardless of which parent purchased them."
• The same bedtime words in both homes. A shared song, phrase or ritual is a thread between the two places.
• Warm talk about the other home. "You'll have fun at Daddy's. Tell me about the park when you get back, if you want to." This gives permission to enjoy both places.
• Play. Some preschoolers play out what is happening: two dolls' houses, a teddy who goes on a trip and comes back. Let the play happen. If you join in, follow their lead rather than turning it into a lesson.

Transitions between homes

Many preschoolers protest at handovers and then settle quickly. A guide for parents from the Massachusetts chapter of the AFCC notes that preschoolers may be upset at transitions "yet once there become settled and happy", and that advance notice and a positive attitude from parents help.

• Tell your child about the change earlier in the day: "After lunch, Mommy is picking you up."
• Keep goodbyes short and warm. Do not sneak away; it makes young children more anxious about people disappearing.
• Keep adult conversations, and especially disagreements, away from the doorstep. AFCC-Ontario says parents should avoid arguments at drop-off and pick-up.
• Let the first half hour in the new home be quiet: a snack, a familiar toy, no questions about the other house.

Our guide to handovers without tears goes into more detail.

What their behaviour may be telling you

Justice Canada lists signs that are common at this age after a separation: fear of abandonment, setbacks such as toileting accidents, clinginess, more anger and tantrums, and headaches or stomach aches. These are a child's way of saying "this is a lot", and most ease as life becomes predictable again.

Going backwards

The Canadian Paediatric Society notes that a younger child "might ask for a pacifier" again and that such reactions are normal "and should get better over time." Respond to regression with comfort, not correction. A 4 year old who wants to be carried, or talks like a baby for a while, is asking to feel small and safe.

Bedwetting

Night wetting is common at this age in general. The Canadian Paediatric Society says that at 5 years of age, 15 percent of children wet the bed, and that most stop between ages 5 and 6. Do not punish or shame it. Talk to a health care provider if your child had been dry overnight for at least 6 months and starts wetting again, since the Society recommends a check in that situation.

Tantrums and anger

Name the feeling, hold the limit, stay close.

Never use the other home as a threat or a reward. It turns a place your child loves into a punishment.

What to do tonight

• Pick the one sentence you will use to explain the two homes, and agree it with the other parent.
• Make or print a simple week calendar with a picture for each home.
• Choose the comfort object that will travel.
• At bedtime, say once more: "It's not because of anything you did. We both love you."
• Message the other parent with anything your child said or asked, briefly and factually, so you both answer the same way.

When to get more help

The Canadian Paediatric Society lists signs that a child may need more support: anxiety, sadness and depression, changes in eating or sleep, trouble at school or child care, and aggressive behaviour. Its advice: "If the behaviour continues or worsens, speak to your doctor." The American Academy of Child and Adolescent Psychiatry notes that young children who are struggling may become "more aggressive and uncooperative" or may withdraw.

Talk to your doctor or a child mental health service if:

• regression, sleep problems or tantrums are getting worse after the first several weeks rather than better;
• your child seems fearful most of the time, or cannot be separated from you even briefly;
• physical complaints like stomach aches keep coming back;
• your child's play or talk often shows themes of being lost, left or hurt.

If your child says anything that suggests they have been harmed or are afraid of someone, stay calm, listen, do not question them in detail, and contact your local child protection agency or your doctor. The professional directory lists therapists who work with young children and families.

What the research says

• Self-blame is the big risk at this age. Pre-schoolers are more likely than older children to blame themselves and to feel threatened by conflict between parents (Early Intervention Foundation review, UK, 2016). The same review found that warm parent-child relationships and secure attachment help protect children, because they are then "less likely to blame themselves."
• Conflict and warmth matter more than the schedule. In an Australian study using national survey data (McIntosh and colleagues, 2011), once parenting, the parents' relationship and socio-economic status were taken into account, care arrangements for 4 and 5 year olds had "no independent effect"; conflict between parents and a lack of warmth explained most of the differences between children. A Swedish study of 3,656 children aged 3 to 5 (Bergström and colleagues, 2018) found that children in joint physical custody had fewer psychological symptoms, on both parent and teacher reports, than children living mostly or only with one parent. Like the Australian study, it is a snapshot in time and cannot show cause and effect.
• Most children recover from the early upset. A review of risk and resilience research (Kelly and Emery, 2003) describes "the resiliency demonstrated by the majority of children" after divorce.

The message for parents of preschoolers is consistent: warmth, and calm between the adults, count for a great deal. You will say "it's not your fault" more times than you can count. Every one of them helps.
