Myths and facts about child development
All ages · 4 min read
Families hear a lot of advice about children who develop differently, and some of it is wrong. Some myths cause guilt, and others cause delay. Here are the ones we hear most, with what is actually known.
Myths and facts
MythAutism is caused by bad parenting or a cold mother.
FactNo. Autism comes from differences in how the brain develops, and it often runs in families. Parents do not cause it.
MythVaccines cause autism.
FactLarge studies in many countries have found no link between vaccines and autism. Please keep your child’s vaccinations up to date.
MythHe will talk when he is ready. Boys always talk late.
FactSome children do catch up, but nobody can tell in advance which ones. A hearing check and a developmental check are quick, and they show whether help is needed.
MythA child who makes eye contact or has friends cannot be autistic.
FactChildren differ widely. Signs can be quieter, especially in girls, and many are missed for years.
MythChildren with ADHD are just naughty or lazy.
FactAttention and impulse control develop differently in ADHD. These children need understanding and support, not more punishment.
MythA label will harm my child, so it is better not to ask.
FactNot knowing harms more than knowing. A clear picture is what opens the door to support, school help and understanding at home.
MythA special diet or supplement can cure autism or ADHD.
FactNo diet or supplement has been shown to cure either. Please talk to a doctor before cutting foods out, because children still need a balanced diet to grow.
MythScreens cause autism.
FactThere is no evidence that screens cause autism. Long hours on a screen can still crowd out talking and play, which children need.
