Step-parents: the role that works for children

You love your partner. You may already care a lot about their children. And you may be finding that the children are polite at best, hostile at worst, and that every attempt to help seems to make something worse. This is one of the most common experiences step-parents describe, and it is rarely about you as a person.

This guide is for step-parents and for the parents who love them. It sets out the role that professional guidance and research suggest works best for children, especially in the early years. For the wider picture of forming a stepfamily, read introducing a new partner and building a blended family.

Start from where the child stands

Patricia Papernow's 2018 review of stepfamily research and practice describes the step-parent as starting in an "outsider" position, while the parent and child are "insiders" with a shared history. Those positions are intense, and they do not change quickly. Children are also dealing with losses, loyalty binds and change.

The AFCC's guide for step-parents explains that children may "feel disloyal if they accept or like a stepparent". A child who is cold to you may be protecting their relationship with their other parent, not rejecting you. The American Academy of Pediatrics notes that children commonly test step-parents, that older children tend to be more critical, and that the best response is not to take it personally.

Three roles, and which one fits

The AFCC describes three common step-parent roles:

• Primary parent.
• "Other parent": the most common role, and often the hardest.
• Friend: common for step-parents who do not live with the child, and often the role older children are most comfortable with.

Most step-parents fall somewhere between "other parent" and "friend", and the right role may change as the child grows. The mistake is assuming you should move straight into a parent's role because you share a home.

Friendship before authority

The AAP describes a new step-parent as, from the child's point of view, "a 'guest in the house'" who needs to build the relationship gradually. The AFCC's advice is: "Don't expect too much too soon."

What builds the relationship:

• Shared interests. Kick a ball, bake, fix a bike, watch their show with them. Activity side by side is easier for most children than talking face to face.
• Small, reliable kindnesses. Remembering the name of their friend, the test they were worried about, how they like their toast.
• Interest without pressure. Ask, then accept a one-word answer.
• Not buying affection. The AFCC warns against trying to buy a stepchild's affection. Gifts are not a shortcut to trust.

Discipline goes through the parent

This is where professional guidance is most consistent:

• The AFCC: "Responsibility for discipline should rest with the biological parent, especially early in the relationship."
• Justice Canada: "At least in the beginning, step-parents should let parents decide on bigger issues like discipline."
• The AAP: step-parents should play "a supportive role in discipline" at first, while the parent remains the primary disciplinarian.

Papernow identifies parenting and discipline as one of the issues that most often divides stepcouples. In practice, that means:

• the couple agrees the house rules in private;
• the parent states them to the children and enforces them;
• the step-parent supports them calmly, and when the parent is not home, holds the line as an adult in charge, not as a new parent;
• the parent makes that delegation explicit. The AAP gives an example of a parent telling a child that while the step-parent is in charge, the child needs to mind what they say "or answer to me".

Never compete with the other parent

The AFCC warns against competing with the child's other biological parent. Children already worry that liking you is a betrayal; competition turns that worry into a choice. Practical rules:

• Never criticise the other parent where the children can hear, even when your partner is upset with them. AFCC-Ontario advises parents to discourage relatives from making derogatory comments; that includes step-parents.
• Stay out of co-parenting communication. The Arizona chapter of the AFCC says step-parents should not send or be copied on co-parenting email, and Justice Canada says not to copy new spouses on messages to the other parent. Your role is to support your partner, not to negotiate for them.
• Keep handovers simple. Justice Canada notes that new partners at exchanges can cause conflict early on. For the first while, it is often easier if you are not there.
• Let children love their other parent openly, in your home, without a reaction from you.

Fairness between children

If you have your own children too, the AFCC is honest that treating every child exactly the same "isn't really possible". Different children have different histories, schedules and needs. Aim for openness about why things differ, and make sure each child gets time alone with their own parent, which the AAP recommends for stepfamilies.

For the parent: make room for the relationship

Step-parents cannot build this alone. A 2020 US study of 291 remarried stepfamily couples by Lawrence Ganong and colleagues found that step-parents made fewer efforts to befriend their stepchildren when they reported the parent was restricting their involvement (what researchers call restrictive gatekeeping). The study also found avoidant step-parents made fewer efforts.

So the parent's job has two parts. Keep discipline and the big decisions in your own hands. And actively make space for your partner and your children to build their own relationship: suggest activities they can do together, speak warmly about each to the other, and do not step in every time things are awkward.

Adoption and bigger steps

Some step-parents eventually adopt a stepchild. The AFCC advises considering adoption only when the relationship is well established. It is a legal step, so get legal advice where you live, and take the child's views seriously.

Look after yourself

Step-parenting can be lonely: lots of responsibility, little authority, and rejection that is hard not to take personally. You are allowed to find it hard, and to feel hurt, while still being the steady adult in the room. On the bad days, hold on to the American Academy of Child and Adolescent Psychiatry's reminder that most stepfamilies do work out their problems, even if it takes several years. Justice Canada points to step-parenting support groups. A counsellor of your own, or a couple therapist who knows stepfamilies, can help you hold the long view. The FairWell directory lists therapists by region.

What the research says

• Papernow (2018) sets out five structural challenges for stepfamilies, including fixed insider and outsider positions and discipline dividing the couple, and warns that first-time family models often do not fit.
• Ganong and colleagues (2020, US, 291 stepfamily couples) found that the parent's restrictive gatekeeping was strongly and negatively associated with step-parents' efforts to befriend stepchildren.
• The American Academy of Child and Adolescent Psychiatry says it may take several years for blended families to fully adjust, and that most stepfamilies do work out their problems.

When to get help

AACAP suggests considering an evaluation if a child shows persistent signs such as persistent anger at a step-parent, feeling torn between households, frequent crying or withdrawal, or loss of enjoyment in usual activities. A family therapist can help the whole household find a workable rhythm. If a child talks about wanting to die or harming themselves, get help now using the lines at the end of this page.
