Guiding Your Child with Autism Through Puberty

The early changes of puberty usually occur between the ages of 9 to 13 years (Odel, 1989). They are noticeable in girls by the budding of breasts and then pubic hair, with menstrual periods starting between 11 to 14 years of age. Boys usually develop testicular enlargement and then pubic hair between the ages of 9 to 14 years. Underarm hair, facial hair and deepening of the voice in boys occur typically between 13 to 16 years. If there are concerns about delayed puberty, or signs of puberty that occur at an earlier age than usual, it may be necessary to refer to a specialist paediatric endocrinologist for an assessment.

Some schools may address puberty and sex education at an age appropriate level, but others may not. Preparation for this discussion is advisable as children with autism need a longer period of time to understand and adjust to changes in their bodies. Even in children who do not have autism, puberty can be a difficult transition due to hormonal changes and mood swings are commonly reported. For a child with autism who cannot understand what is going on, it can be so much harder and behaviours such as emotional swings, aggression, self-harming and masturbation can sometimes be escalated (Paul, 2008). In children with Autism Spectrum Disorders (ASD) or special needs, communication issues are common and many children may not be able to express their emotions (Osterlin et al, 1994).

Help your child understand and cope with visual aids and be explicit in your language and communication with a child with autism (Charlop-Christy MH, 2002). Explain and use labelled pictures to explain about when puberty happens and how each part of the body will change including what fluids will come out- such as sweat, tears, semen, menstrual blood, and vaginal discharge. The use of visual aids will often help with developing a routine for hygiene in a step-by-step manner such as which parts of the body are needed to pay special attention to in the bath or shower, how to shave and how use a menstrual pad. Do not “assume knowledge” in your child (Light et al, 1998).

During pubertal years, it is not uncommon to have sexual urges and your child may masturbate. This is a healthy and normal part of pubertal development. It is important to explain and discuss and reassure and some of these new sensations can cause anxieties. Teach your child the difference between being in public and in private, and that some activities could only happen in private such as undressing or masturbation. Teach your child safety; how to say “no,” that he /she should not let anyone touch his/her private parts, that he/she should never touch anyone else’s, and that he/she should tell you if anything like this ever happened. Note that child sexual abuse and exploitation is higher in children with special needs (Tharinger et al, 1990).

Many adolescents can begin to develop a romantic interest in the opposite sex, or same sex. Help your child to understand these feelings and what sexual relationships are. This can be supported by using social stories and visual drawings using stick figures or photographs. It is likely that your child may already have developed a curiosity about the topic. If he/she shows an awareness, be prepared to discuss this and let them ask you questions. Topics can progress through from what is sexual intercourse, to gaining sexual consent and the importance of protected sex as they develop further understanding.

Puberty is an important developmental stage with changes that occur physically, emotionally and socially. As parents and caregivers, puberty can be challenging and being prepared and informed on how to approach any issue as they arise is advisable.
