Sexual development of children

When parents or carers talk to children about their bodies and about sexual behaviour and feelings, children learn that it's okay to talk about these things. Just as it is important for parents and carers to know about how a child grows and develops it is important to know about children’s sexual development.

Children have sexual feelings from birth. Baby boys can have erections and boys and girls can get good feelings from touching the sexual parts of their bodies.

Babies usually explore their genitals (the sexual parts of their bodies) when their nappies are off.

Under three year olds do not understand that all their body parts are really part of them, so young boys may be worried that they might lose their penis when they see that girls don't have one, or girls may worry because they do not have a penis.

Preschool children are often not modest about their bodies and like being naked.

They are interested in looking at their own and other children's bodies. They may play games, which involve looking and touching.

They are often interested in parents' bodies and are interested in where babies come from and how they get out of the mother's body.

Four year olds are very interested in toilet words and in what people do in bathrooms and toilets. They don't usually understand or ask about sexual intercourse.

In the early primary school years -Children usually know that looking at each other's bodies and masturbation are things people do in private.

Children often use sex words that they have heard from their friends.

By mid primary years there is likely to be embarrassment about nudity and modesty in front of parents as well as others. There is the beginning of sex talk and joking with peers. Sex play may include kissing games, teasing and pretend games about marriage.

Masturbation

In early childhood touching of the genitals may be:

By early school years children have learnt that masturbation is something that is done in private.

If children masturbate a lot it may be because something is worrying them. It is important to try to work out what is the matter. Very young children can't tell you so you need to think about what could be the cause (for example: new baby, starting child care), and then work out how to help them feel better.

Give children who are masturbating something else to do with their hands, such as reading a book.

Touch

Some fathers and stepfathers worry about cuddling or holding their daughters because of fears about being accused of sexual abuse.

However, touching, such as hugging, stroking and cuddling, is very important for children to feel loved and to learn to show love and affection. Touching children should be done as part of caring for the child not because adults want to do it for their own sexual pleasure.

What parents and carers can do

Most parents want their children to have a healthy attitude about sex. Remember, your attitude to the opposite sex, and the way you behave, react and talk about sex, will influence how your children respond and feel about their sexuality.

Sex play

If you find children playing sex games

Many things which children find confusing or frightening are caused by the way adults react. If you find children playing sex games and you are not sure how to react, take a deep breath and think first.

Think about the message you want to get across to children. You could start with something like "I see you are playing a game about your bodies, can you tell me how you thought of that game?"

"There are lots of way to learn about bodies, one is by touching someone else, another is by looking in books. If you would like I will show you some books", and invite the children to come with you to find a book.

When you need help about children's sexual behaviour

There are some things that children say and do which might mean that someone has been abusing them. If this happens children need adults to protect them and keep them safe.

How can I tell when a sexual behaviour is a problem?

Assess:

  1. whether the type of sexual activity is normally expected for the child's developmental level
  2. whether the children involved have relatively equal power
  3. whether force or intimidation was used
  4. whether the behaviour is kept secret
  5. whether the behaviour appears compulsive or the child is obsessed with it.

Talk it over with a doctor or a social worker if you find children:

Signs of stress such as bedwetting, soiling their pants or hurting themselves may be signs of sexual abuse but can be caused by other worries. They may reflect signs of stress and your child needs help.

It is most important that children who have been sexually abused understand that they are in no way to blame for what happened to them.
