For all children every milestone achieved is a testament to the unique and intricate process unfolding within each young mind. For autistic children, this journey may present a distinct pattern, with some reaching developmental milestones like crawling, walking, and talking later than their neurotypical peers. Let’s have a look into the fascinating realm of Autism and explore why some autistic children might crawl, walk, and talk later, shedding light on the underlying factors contributing to this unique way of developing.

1. Individual Pacing:

Child development is not a one-size-fits-all journey. Each child, whether neurotypical or autistic, has a unique timeline for achieving milestones. Autistic children, like any other children, follow their own pacing. This individual rhythm might lead them to focus on one set of skills before they progress to others. Like some neurotypical children might focus on talking earlier than walking, autistic children might prioritise other areas before crawling or talking.

2. Neurodevelopmental Complexity:

The human brain is a remarkable entity, with a bewildering array of interconnected processes that lead to us achieving our developmental milestones. Autistic children often have variations in “neural wiring”, which can impact the balance between gross motor skills (crawling, walking) and fine motor skills. Speech and language acquisition falls under fine motor skills and may be momentarily disrupted due to the divergent neurological pathways at play in autism.

2. Sensory Processing Differences:

One of the hallmarks of autism is altered sensory processing. Autistic children often experience sensory stimuli differently than their neurotypical peers. This heightened or diminished sensitivity can influence a child’s desire or ability to engage in activities like crawling and walking. The sensation of movement while crawling or walking, for instance, might be overwhelming for some autistic children, causing them to either avoid or delay these activities.

3. Visual-Spatial Abilities:

Autistic children and adults frequently display excellent visual-spatial abilities. This strength might lead some children to focus more on activities that engage these skills, potentially delaying their engagement with activities like walking or talking. As they navigate their environment and process information visually, they might naturally invest more time in activities that stimulate this particular cognitive ability and strength.

4. Communication Challenges:

For many autistic children, speaking can be a really complex and difficult endeavour. Communication delays are a common feature of autism. This can affect both receptive and expressive language development. While some children might be physically capable of crawling or walking, they may not yet have the tools to communicate their desires and intentions. This leads to a temporary focus on non-speaking forms of expression. This does not mean that they do not communicate at all. But autistic individuals often start out using jargoning or echolalia as a form of communication as well as behaviours and physical forms of communication.

5. Executive Functioning and Motor Skills:

Executive functioning, or abilities for planning, organising, and carrying out tasks, can vary in autistic children. These skills are crucial for activities like crawling, walking, and talking, which need coordination and planning. About 40% of autistic persons have a motor planning difficulty.

6. Intense Interests and Routines:

Autistic children often develop intense interests in specific subjects, sometimes to the exclusion of other activities. These interests might become their primary mode of engagement. They might side-line milestones like crawling, walking, or talking. The mostly rigid adherence to routines and preferences might cause them to allocate more time to their preferred activities. This delays their engagement with other developmental tasks.

How can Speech and Language Therapy help:

Support and Intervention:

Early intervention and regular Speech and Language Therapy play a pivotal role in the developmental journey of autistic children. Therapies tailored to individual needs can aid in bridging the gaps between milestones. Occupational therapy, for example, can help address sensory sensitivities and motor skill challenges that might impact crawling and walking. Speech therapy can help communication development, gradually bridging the gap between non-verbal expressions and spoken language.

For example, we now know that echolalia or jargoning of longer phrases with intonation, repeating scripts from favourite tv shows or songs have many meanings and communicative functions. For example, a child who utters long strings of echolalic utterances, often difficult to understand, might want to do any one of the following:

• Comment
• greet
• ask a question
• make a request
• express surprise
• negate something.

We now understand that the way to support a child with echolalia is to acknowledge all utterances and try and find out what the meaning is behind these scripts. This is very supportive. Over time it will lead a child to move on to understanding and saying more clear and self-generated language.

Conclusion

In conclusion, the journey of an autistic child’s development is a testament to the uniqueness and complexity of the human mind. The delays or differences in achieving milestones like crawling, walking, and talking can be attributed to a range of factors, including

• neurodevelopmental intricacies,
• sensory processing variations,
• and communication challenges.

It’s crucial to recognise that these delays are not indicative of a lack of potential, but rather a manifestation of the intricate interplay between an autistic child’s strengths and challenges. By embracing these differences and providing tailored support, we can help each autistic child unfold their potential at their own pace.
