Raising multiple children presents unique challenges for any family, but when one child is on the autism spectrum, parents face an entirely different set of considerations. With autism spectrum disorder (ASD) affecting approximately 1 in 31 children in the United States, many families are navigating this complex journey while ensuring all their children receive the attention, support, and love they need.
Understanding the Current Landscape of Autism
The prevalence of autism has risen significantly in recent years. About 1 in 31 (3.2%) children aged 8 years has been identified with ASD according to estimates from CDC’s ADDM Network, representing a substantial increase from previous decades. While 6.7 in 1,000 children were diagnosed with autism spectrum disorder (ASD) in 2000, that number had risen to 27.6 in 1,000 children by 2020. This means that currently 1 in 36 children in the U.S. get diagnosed with ASD, up from 1 in 150 children 20 years ago.
Additionally, ASD is over 3 times more common among boys than among girls, and autism prevalence is lower among white children than other racial and ethnic groups, with Hispanic, Black, Asian or Pacific Islander, and American Indian or Alaska Native children showing higher prevalence rates.
The Unique Dynamics of Multiple Children with One on the Spectrum
Understanding Sibling Relationships
When one child in the family has autism, the entire family dynamic shifts. Research shows that autistic people who have siblings develop better social skills as well as a built-in resilience. However, the odds of individuals having “more negative” relationships with their autistic siblings were 1.5 to 3.0 times the odds of comparison groups compared to typical sibling pairs.
Despite these challenges, while an autism diagnosis can challenge the unique relationship between siblings, all siblings can learn from each other, bring out the best in each other, and have positive and meaningful relationships. Siblings of autistic children generally feel positive about their brothers or sisters, but sometimes their relationships aren’t as close as they could be.
The Emotional Impact on Neurotypical Siblings
Siblings of children with autism often experience a complex range of emotions. Because anxiety and depression are more common among siblings of autistic people, it’s important to assure that support and care are readily available. As a sibling this may make you feel angry, sad, jealous, frustrated and/or confused.
However, many siblings also report positive outcomes. Many siblings of people with autism learn important life lessons and develop maturity, tolerance, loyalty and empathy as well as increased self-concept and social competence. They’re learning important lessons about respecting individual differences, fairness and unconditional love.
Practical Strategies for Managing Multiple Children
1. Establish Clear Communication About Autism
One of the most crucial steps in managing a household with multiple children is fostering understanding. You can strengthen your children’s relationships with each other by explaining and talking about autism. Conversations about autism ensure your children have accurate information, which can help to reduce anxiety or confusion.
The first step to helping siblings understand autism is to start talking about autism when they begin to understand or notice differences. Adapt the conversation based on their age and understanding. Ask what they already know, use age-appropriate language, and be prepared to explain multiple times. Open communication fosters understanding and empathy among siblings, creating a supportive family environment.
2. Create Structured Routines for the Entire Family
For families with multiple children including one on the spectrum, routine becomes even more critical. One of the best things for our family has been establishing a routine. This is important for one child but really important for the structure of the family when there is more than one child with autism in the household.
When managing multiple autistic children, you can deal with multiple autistic kids by identifying the different sensory problems, establishing routines, being fair, adjusting your discipline strategies, and communicating with them.
3. Ensure Individual Attention for Each Child
It’s good for all children to have one-on-one time with their parents, but it can be especially helpful for siblings of autistic children. One-on-one time sends the message that each of your children is special and their feelings and experiences all matter to you. This is good for their confidence and sense of belonging to your family. And when your children feel positive about themselves, it can be good for their relationship with their sibling.
Parents can also ensure that every child in the family gets needed attention and permission to pursue their own dreams.
4. Address Different Sensory Needs
When dealing with multiple children where one or more are on the spectrum, understanding sensory differences is crucial. Each child with autism falls on a distinct spectrum of sensory processing and will have specific sensory needs, seeking tendencies, and avoidance tendencies.
5. Foster Meaningful Sibling Connections
One way to encourage closer relationships among your children is to look for ways that they can all play, have fun and interact together. For example, your children might all enjoy playing with sand or trains or playing basketball.
While every sibling relationship is special, the communication and socialization deficits inherent in autism diagnoses can make sibling bonding more difficult. Creating opportunities for younger children to play together or helping older siblings to find common interests, even if it’s as simple as doing a puzzle together or playing a video game, can go a long way in increasing the quality and quantity of interactions and ultimately building sibling bonds.
Managing Fairness and Different Needs
Balancing Different Requirements
One of the most challenging aspects of parenting multiple children with one on the spectrum is balancing different needs while maintaining fairness. It might be easy for a family to invest all of their time and money into the child that is more severe. However, the child that is on the higher end of the spectrum needs just as much help with their challenges but in a different way. Whether you have two or more children on the spectrum, they all need to be offered the same amount of therapy to help them achieve strengths through their challenges.
What I do for Trenton doesn’t necessarily have to be done for Andrew. Therefore, even though it may take more time and more planning, I have to meet each child’s unique needs. Whether it is preparing for our next day or how they are rewarded for good behavior, both get what they need in a way that meets their needs.
Creating Family Unity
I talk to the boys and teach them that we are in this journey together. If one of us can’t handle something then we all support the one who is unable to do it. For instance, sometimes my son Trenton is unable to do something due to his severe challenges with autism. If we are somewhere and Trenton needs to leave or can’t do it, then we leave as a family. This has displayed so much to my boys. It has taught Andrew to accept his brother’s challenges and it doesn’t make Trenton feel left out.
Understanding Multiple Children with Autism (Multiplex Families)
Genetic Considerations
Some families have multiple children with autism, known as “multiplex families.” A recent prospective study from the Baby Siblings Research Consortium found that children with two or more siblings with autism spectrum disorder (ASD) were more than twice as likely to be classified as having ASD at age 3 than children with only one sibling with ASD.
Previous twin and family studies have shown that ASD has a strong genetic component, with a heritability of about 80%. A genetics work-up is recommended for all children with ASD.
Parenting Multiple Children with Autism
Amanda Olsen says parenting a child with autism is like being a tour guide – someone who must translate the customs and language of the nonautistic world. But when you have two children with autism, like she does, the job is considerably more complicated. That’s because many siblings with autism fall along different parts of the spectrum, and her daughters are no exception. “I’m my children’s tour guide to the world, only I’m touring two different children in two different countries – one’s in France and one’s in Spain – at the same time. I’m having to break down the language and cultural differences and customs of two countries for them,” she explained. If that sounds challenging, that’s because it is.
Building Support Systems
Professional Support
A sibling support group can help your children realise they’re not alone and understand that their feelings are natural. A sibling support group might also improve your children’s relationships with each other.
Family Support Networks
When you begin learning about autism, there are moments when you will feel lonely and lost. You will learn more from your “support friends and family” than an autism expert. Simply talking to and listening to others who are raising autistic children can be life changing.
Long-term Considerations and Future Planning
Preparing for Adulthood
Communication is key to building healthy relationships and smooth transitions among family members. Brothers and sisters, or siblings, are often key players for autistic adults and their caregivers, especially during transitional times.
You might be concerned about the future care needs of your autistic sibling (if they have high support needs), particularly when your parents are no longer able to be their primary carers. It may be useful to meet as a family to talk about ideal care options for your autistic sibling in the future. Your sibling should be included in this if possible, using whatever means of communication that will give them the opportunity to express their views.
Maintaining Parental Well-being
Self-Care Strategies
When you’re looking after an autistic child, it’s also important to take care of yourself. Being emotionally strong allows you to be the best parent you can be to your child in need. These parenting tips can help by making life with an autistic child easier.
It may sound trivial, but sleep is a huge factor in families that have children with ASD, and affects both a child’s behavior and quality of family life. No one functions well with chronic sleep deprivation. I never had more than 4 hours of broken sleep for 7 years which greatly affected my ability to make good decisions and tried my patience both at work and home.
Building Confidence Through Knowledge
For me, feeling empowered changed my life outlook. I obtained this empowerment through reading books and attending trainings in the field of autism. The more knowledge I gained, the better I felt about my parenting situation with 2 children on the spectrum because I knew their challenges were not a result of my parenting. I also felt better equipped to deal with medical appointments, therapies, and dealing with the school. If you don’t know what questions to ask, it can be hard to get direction with solutions and coping strategies. Acquiring information also gave me valuable tools to help my children.
Positive Parenting Approaches
Focus on Strengths
Theodore Roosevelt said, “Comparison is the thief of joy.” Every person – you and I included – is a combination of positive traits and plenty of flaws. Choose to see your child’s positive traits rather than focusing on their challenges. When you visit the doctor or therapist, rather than detailing the challenging behaviors and deficits, focus on their strengths. When we trot out an itemized list of our children’s flaws, we are comparing our autistic child to others, and destroying our children’s self-esteem.
Realistic Expectations
My opinion, all parents of autistic children should receive a merit badge in parenting. Raising an autistic child is like learning a foreign language – but in parenting. It is challenging and sometimes overwhelming. Parents utilize numerous resources to help their child developmentally, but they still worry they are not doing a good enough job. Your child does not need the perfect parent, they need a happy and supportive one. Raising an autistic child is difficult, but it is empowering and will make you a better person.
Conclusion: Embracing the Journey
Parenting multiple children when one is on the autism spectrum requires patience, understanding, and adaptability. While the challenges are real and significant, the rewards can be equally profound. Most siblings of children with autism end up being compassionate human beings who treasure their siblings and who note both the struggles and the strength that the family experienced because of being touched by autism.
On some days, I feel like I fail. However, other days, I feel like we are doing awesome. There will always be days where you will feel like nothing works. Nonetheless, don’t give up! It takes a lot of patience and multiple trial and errors until you find what works for you and your family.
Remember that every family’s journey is unique, and what works for one family may not work for another. The key is to remain flexible, seek support when needed, and celebrate the small victories along the way. With proper support, understanding, and strategies, families can thrive and all children – whether neurotypical or on the spectrum – can reach their full potential.
