Autistic girls may be quieter, hide their feelings and appear to cope better in social situations, the NHS reports.
This might make it harder to spot autism in girls.
If you’re concerned about any signs your child is showing, talk to your GP, National Autism Center advises.
Other places where you could seek advice according to the NHS are health visitors, special educational needs (SENCO) staff at your child’s school or any other health professional your child sees.
