Gender identity refers to the deep and intimate feeling a person has of themselves. Children begin to understand and express their gender identity early in life.

This article discusses how gender identity typically develops and how parents and caregivers can promote healthy development of gender identity and expression in children. It’s important to remember that each child is unique and may develop at a different pace.

What we mean by gender: Some useful definitions

Sex at birth: When children are born, sex is assigned based on external genitalia. A child who has a penis is said to be male. A child who has a vulva is said to be female. A child who is born with reproductive or sexual anatomy that doesn’t fit the description of “female” or “male is referred to as an intersex child.

Gender identity: Gender identity is “who you know yourself to be”. It is important to know that gender identity exists on a spectrum. A person’s gender identity can be masculine, feminine, or other.

Gender expression: This is how you express your gender to others, whether through behaviour, clothing, hairstyle, the name you choose to go by, etc. Words to describe someone’s gender expression could be “masculine,” “feminine,” “androgynous,” etc.

Sexual orientation: This refers to sexual or emotional attraction that one feels for another person.

Transgender: When a person’s gender identity is not the same as the assigned sex at birth, they may be referred to as “transgender” (often shortened to “trans”). For example, a child born with female genitalia may identify as a boy. A child may also say that they are not a boy or a girl, but just “themselves” because they don’t want their sexual characteristics to define who they are. Some cultures and Indigenous people use the term “two-spirit” to represent a person who embodies both a masculine and feminine spirit. Two-spiritedness has many subtleties of a spiritual and cultural nature.

Gender dysphoria: Describes the level of discomfort or suffering that can exist when there is conflict between the assigned sex at birth and gender identity. Some transgender children experience no distress about their bodies, while others may express significant discomfort. This distress can be more obvious as puberty begins and the body starts to change.

How does gender identity develop?

Here is what you can typically expect at different ages:

  • 2 to 3 years old:
    • At around 2 years old, children are aware of differences between boys and girls.
    • Most children can identify themselves as a “boy” or “girl”. This term may or may not match the assigned sex at birth.
    • Some children’s gender identity remains stable over their life, while others may alternate between identifying themselves as “boy” or “girl”, or even assume other gender identities at different times (sometimes even in the same day). This is normal and healthy.
  • 4 to 5 years old:
    • While many children at this age have a stable gender identity, gender identity may change later in life.
    • Children become more aware of gender expectations or stereotypes as they grow older. For example, they may think that certain toys are only for girls or boys.
    • Some children may express their gender very strongly. For example, a child might go through a stage of insisting on wearing a dress every day, or refusing to wear a dress even on special occasions.
  • 6 to 7 years old:
    • Many children begin to reduce outward expressions of gender as they feel more confident that others recognize their gender. For example, a girl may not feel that she has to wear a dress every day because she knows that others see her as a girl no matter what she wears.
    • Children who feel their gender identity is different from the assigned sex at birth may experience increased social anxiety because they want to be like their peers, but realize they don’t feel the same way.
  • 8 years old and up:
    • Most children will continue to have a gender identify that matches the assigned sex at birth.
    • Pre-teens and teens continue to develop their gender identity through personal reflection and with input from their social environment, like peers, family and friends.
    • Some gender-stereotyped behaviours may appear. You may notice your teen or pre-teen making efforts to “play up” or “downplay” some of their body’s physical changes.
    • As puberty begins, some youth may realize that their gender identity is different from their assigned sex at birth.
    • Because some children’s gender identification may change, especially around puberty, families are encouraged to keep options open for their child.

How do most children express their gender identity?

Younger children may express their gender very clearly. For example, they may say “I am a she, not a he!”, “I am not your daughter, I am your son.”

Children may also express their gender through their:

  • Clothing or hairstyle
  • Choice of toys, games, and sports
  • Social relationships, including the gender of friends
  • Preferred name or nickname

Hot Parent tip: Gender expression is different from gender identity. You can’t assume a child’s gender identity based on their gender expression (for example, their choice of toys, clothing, or friends).

My boy likes to wear dresses. Should I let him?

Some children go through a phase of resisting gender expectations. Remember that gender expression and gender identity are two different things. The way you express yourself does not necessarily define your gender.

Children do best when their parents or caregivers show them that they are loved and accepted for who they are.  Discouraging your child from expressing a gender can make them feel ashamed. Give them unconditional support. In doing so, you are not framing a gender, but simply accepting who they are and how they are feeling.

For many children, this is a phase. No one can tell you whether your child’s gender identity or expression will change over time. What children need to know most is that you will love and accept them as they figure out their place in the world. In older children, you can also gently help prepare them for negative reactions from other children, for example, by role-playing how best to confidently respond to teasing.

What does gender-creative mean?

Gender-creative children express their gender differently from what society may expect. For example, a boy who wants to wear dresses might be considered “gender-creative”. Society’s expectations for gender constantly change and vary in different cultures and at different times in history.

I think my child may be transgender. What should I do next?

Gender diversity is not a result of illness or parenting style. It isn’t caused by letting your child play with dolls or trucks.

If your child is transgender or gender-creative, they can live a happy and healthy life. Here are some tips to support them:

  • Get support from other parents of transgender and gender-creative children
  • Talk to a mental health professional who specializes in the care of transgender and gender-creative children (if available in your community).
  • Indigenous families can talk to a two-spirit elder or leader
  • Connect with local resources to talk with other parents about their experiences. in Manitoba look for parent run groups.
  • Look for ways to support exploration in clothing, toys, hair styles, play, and activity choices.
  • Check in to see if they would like to be called a different name – a chosen name that you can decide on together.
  • Ask what pronouns they would like to use.

What does it mean to transition?

For young children transitions are social and can include:

  • Updating chosen names and pronouns with schools, daycares, family and friends
  • Ask your child if they would like everyone (family and friends) to be using their updated pronouns and chosen name. Your child will let you know when they are ready to make these changes, and they may have already shared this with friends, daycare, or preschool.
  • Possibly adding new clothing to their wardrobe or having a different hairstyle

There are no medical procedures or medications that preschool children need or could have to change their bodies.

When do I make changes to legal documents or at pre-school or daycare?

  • People will make changes to legal name, and gender on birth certificates, at various times. You and your child will find the best time to do this for your family.
  • Schools can update names and gender anytime at your request.
  • Check in with your child to see if they would like to have their pronouns and name updated with school or daycare.

How can I support my child?

Strong parent support is key!

  • Love your child for who they are.
  • Talk with your child about gender identity. As soon as your child is able to say words like “girl” and “boy,” they are beginning to understand gender.
  • Ask questions! This is a great way to hear your child’s ideas about gender.
  • Read books with your child that talk about many different ways to be a boy, a girl, or having another gender identity.
  • Don’t pressure your child to change who they are.
  • Find opportunities to show your child that transgender and gender-diverse people exist and belong to many communities who appreciate and love them.
  • Ask your child’s teachers how they support gender expression and what they teach about gender identity at school.
  • Be aware that a child who is worrying about gender may show signs of depression, anxiety, and poor concentration. They may not want to go to school.
  • Be aware of potentially negative issues that your child may face. Let your child know that you want to hear about any bullying or intimidation towards them.
  • If you are concerned about your child’s emotional health, talk to your child’s family doctor, paediatrician, or other mental health professionals that specialize in the care of transgender and gender-creative children.
  • Some parents have a hard time accepting that their child’s gender identity is different from the assigned sex at birth, often in cultures and religions where this is not easily accepted. If you are having difficulties, please seek additional help through websites, printed resources, support groups or mental health providers. See below for additional resources.
