Puberty and body changes can sometimes feel like they happened overnight. Many changes happen throughout puberty and it can be hard to know what is ‘normal’. Supporting children with intellectual disability and autism spectrum disorder to learn about, prepare for and manage their body changes can also feel like a daunting task.
Unfortunately there is no set age when puberty will begin, and no set order in which the changes will happen. In girls, puberty can start anywhere between the ages of 8 and 13. Boys tend to start puberty later, usually between the ages of 10 and 15.
Since you can’t tell whether your child will start puberty earlier or later, this means that you need to start preparing your child for puberty earlier than you might have thought.
