Infographic; 18-year-old child development milestones

Do you understand child development milestones? This infographic explains what development milestones your 18-year-old will have achieved.

Child Development at the age of 18

My oldest daughter turned 18 in September 2021 and although she’s now technically an adult, she’s still our child. We’ve seen her go through so many, physical and emotional changes over the years, but we’re yet to fully understand the mind of a teenager.

By the age of 18, many teenagers are feeling a combination of excitement and uncertainty about their future. They’ve got a lot of decisions to make about life. They spend an awful lot of time thinking and talking about the life they would like, once they’re finished their education.

The 18-year-olds with a lot of life skills, seem to, overnight, develop an adult mindset and have an instant change in outlook on their future. Others may regress slightly and proceed with caution.

Interestingly and ironically, at 18 your child’s brain still isn’t fully developed. However, at the age of 18, they can legally buy alcohol. A fact that can evade teenagers is that drinking alcohol at 18, (or younger) could potentially affect the brain and cognitive development.


I’ve put together an infographic briefly explaining the child development milestones of an 18-year-old. I hope you find it informative.

I’m not one for telling people how to parent. You do you. But it’s important to note, that once your child hits 18, parenting doesn’t stop.

My oldest daughter has complete freedom now, she’s an adult after all. However, Mrs F and I are still here to advise and guide her, if and when she needs it.
