Autism and babies: the relationship between crying and early diagnosis

Autism is a developmental disorder that variably affects individuals’ communication, social interactions, and behaviour. The early identification of signs of autism in babies is crucial in enabling appropriate support and improving their learning abilities and quality of life. This raises the following question: is there a particular link between babies who do not cry and autism? In this article, we attempt to determine whether there are any relevant studies or observations on this subject.

Understanding babies’ crying

Crying is an essential means of communication for infants. As they are unable to produce coherent words or sentences, babies use their cries to express their needs and wants. Several reasons can explain why a baby cries:

Hunger

Discomfort (dirty diaper, too hot or cold)

Need for affection or cuddles

Boredom

Pain (colic, teething, etc.)

Moreover, every baby has their own crying intensity, as well as their own way of managing their emotions and reacting to their environment. Some babies are naturally calmer and cry less than others.

The question of autism in babies who do not cry

Within autism research, certain studies have sought to establish a link between the way babies cry and their subsequent development. Indeed, some early signs of autism can manifest in the first months of life, notably:

An avoidant or unfocused gaze

Little interest in faces

A limited response to social stimuli (smiles, laughter, etc.)

Stereotyped movements

It is therefore logical to ask whether babies who do not cry might be at greater risk of later developing an autism spectrum disorder. However, it should be noted that no study has definitively established a direct correlation between the absence of crying and autism.

Crying and autism: current observations

1. The quality of crying in autism

Some research has nonetheless examined the characteristics of crying in children with autism spectrum disorders. These studies have generally observed differences in the quality of crying rather than its absence. For example, one study showed that the cries of babies later diagnosed with autism could be perceived as higher-pitched and less comforting for the listener.

2. Responsiveness to crying in autistic children

Other research has looked at the way children with autism spectrum disorders respond to other babies’ cries. These studies have shown that autistic children may display a reduced responsiveness to crying compared to non-autistic children. This does not necessarily mean that they themselves do not cry, but their emotional response to crying may be different.

3. Self-soothing behaviours in autistic babies

Some babies presenting with an autism spectrum disorder may develop unusual self-soothing behaviours, such as rocking, scratching, or rubbing themselves. These behaviours may help the baby channel their emotions and reduce the number and intensity of their cries. However, it is important to emphasise that not all children who display these behaviours will necessarily receive a diagnosis of autism.

Provisional conclusion: caution and vigilance

In sum, although certain research has highlighted differences in the quality of crying and responsiveness to crying in children with autism spectrum disorders, no study has formally established a link between the absence of crying in babies and autism. It is therefore important to be cautious and not to draw hasty conclusions.

If you are concerned about your child’s development, it is recommended that you consult a healthcare professional in order to obtain informed medical advice. Only a specialist doctor will be able to determine whether your child’s development is following its normal course or whether further investigations are warranted.
