Understanding autism in babies can be reassuring and empowering for parents and carers. While autism is usually diagnosed around the age of 4 or 5, some early signs can appear during the first year of life. In this post, we'll walk you through what to look out for, how to get an autism diagnosis for your child in the UK, and what support you may be entitled to.

While babies with autism may not look different physically, their behaviour and development can be noticeably different.
Most parents begin to notice early signs of autism in babies by the age of 2, but some signs can appear as early as 2–6 months. It's usually not about strange behaviours—it's more about what your child isn't doing compared to other babies their age.
If you've noticed a few of these early signs of autism in babies, don't panic—but do act. Early intervention makes a big difference.
