What are the signs of FASD?

Foetal alcohol spectrum disorder (FASD) is a neurodevelopmental disorder caused by exposure to alcohol before birth. You can learn more about what it is in our article ‘What is FASD?’

Approximately 5% of children with FASD are diagnosed at birth, but for most, the signs don’t appear until they are around 18 months to two years of age.

While some children with FASD may show behavioural problems at pre-school and early primary school years, other children may not show behavioural and cognitive problems until they are aged eight or nine – and without support, the gap between them and their peers widens.

Getting an early diagnosis of FASD changes lives, giving you and your child a starting point to get support that you both need. Many whānau say receiving the diagnosis for their child took away the confusion and frustration that weighed them down.

What a pleasure it’s been to join the Awhi team. I get to spend my days researching information that supports me as a parent, and sometimes challenges me to rethink what I thought I knew. My hope is that it will be useful to you too. I live in Kapiti with my partner and two teenage boys, and spend as much time as possible in the surrounding bush and at the beach.
