HELP: I Need Communication Advice for Autistic Grandson

November 2, 2021

A grandfather from Singapore asks…

My eldest grandson (age 5) is autistic. His parents work full-time so I am his caretaker.  He is very picky about his food, does not talk, is hyperactive, walks on his toes, has difficulty concentrating, wakes up in the middle of the night, is not potty-trained, and fiddles with his fingers. We do a gluten-free / casein-free diet, supplements to detoxify his body of metals, soft laser treatments on his brain, and essential oils. Our main concern is how to reduce his hyperactivity and improve his language. Please help.


Hi Grandpa! It is clear from your letter that you absolutely adore your grandson and would do anything to help him. Your love really shines through. What else stands out to me about your letter is that your family is trying a lot of biomedical approaches to help your grandson, but there was no mention of any behavioral interventions. As a behavior analyst I’m not familiar with the research on any of those treatments you mentioned, but I know the research is very clear on the effectiveness of behavioral therapy for those with autism.

There are thousands of studies, across several decades and multiple countries, which have concluded that Applied Behavior Analysis is effective in reducing problem behaviors (like disruptive hyperactivity) and increasing adaptive behaviors (like communicating and potty-training). In fact, applied behavior analysis (ABA) is the most well-researched and most proven intervention for autism.

With that said, let’s go over some behavior basics:

  • In order to change a behavior you must first identify what the function of that behavior is. Does he do it to get attention? Does he do it to get access to an item or activity? Does he do it because it feels good? Does he do it to escape a task, demand, or activity? You MUST know why your grandson does something before you can know how to respond to it.
  • Whenever we want to reduce a behavior we MUST provide a replacement. For example- If you want your grandson to stop running around in the house you must give him an alternative. Maybe the alternative is jumping on a trampoline or running around at the park.
  • To increase a behavior you want to see more of, you must reinforce it. For example — if your grandson loves cookies you can use cookies as a consequence (reward) for communicating.
  • Consistency is key! If you apply a strategy only some of the time your grandson’s behavior will not change.

Next, here are some tips on managing hyperactivity:

  • Provide your grandson a functional way to expend some energy. Physical activity such as outdoor play may help. Some other things to try might be climbing, jumping, dancing, or silly movements like wheel-barrows, jumping jacks, or bear crawls.
  • Set him up with small tasks when he needs to get things done. For example, if he needs to do homework but has a hard time paying attention, have him do only a few minutes at a time. Reward him for completing partial tasks. Maybe this means doing three math problems then getting a break. Or perhaps it’s writing three spelling words then getting to jump on the trampoline for one minute. Make it a simple “First ____ Then _____,”with something really exciting as the consequence.
  • Create a visual schedule for him to use at home. This may help organize him and prepare him for what’s in store. Additionally, this may help him attend to non-preferred tasks because he will be able to see that something preferred is coming up next. Use pictures so he can understand. It might be something like this:



Lastly, here are strategies for improving communication:

  • Always remember that communication is not necessarily talking. We all communicate in a variety of ways: through gestures, facial expressions, tone of voice, posture, crying, etc. So for your grandson keep in mind that he may need to communicate with you in some way other than using his voice. Maybe he needs pictures or perhaps he knows sign language. Be open-minded to however he is able to communicate. While you can always strive for vocalizations, know that there are many other ways to communicate with you.
  • Create lots of opportunities for your grandson to ask for things. Move all of his favorite items out of reach so that when he wants something you can withhold it until he asks for it. You can even put preferred items into clear jars so that he can see them but will need help to open the jar and get the item. This forces him to interact with another person in order to get what he wants. As parents and grandparents it’s easy to anticipate the child’s needs. But it’s important not to rob your grandson of the opportunity to communicate with you. In order to promote language you have to give him the chance to need If all his needs are already met he will never need to communicate. For example — if he is trying to operate a toy and can’t do it, don’t jump in and do it for him. Instead you can say “Help?” and try and get him to ask for help opening it.
  • Focus on IMPORTANT language and leave all other words out! Oftentimes families tend to focus on things like the alphabet, numbers, shapes, colors, or polite words. Your grandson needs to get his needs met, not learn academics, at home. Focus on foods, drinks, toys, people, etc. Also, don’t force him to use words like “please” or “thank you.” Those are meaningless at this point. Keep it short and simple! Start with one word requests.
  • When you know what he wants, show him the item and say the name of it (or show him the picture icon of it, or model the sign for it- depending on how he is going to communicate). For example — you may hold a cookie and say to him, “Cookie.” If he makes any attempt to ask for it, even if he mumbles “buh,” give him that cookie! Or, let’s say you’re using sign language and you hold the cookie then demonstrate the sign for “cookie.” If he makes any attempt to motion with his hands, give him the cookie. As he gets more fluent with asking for the item you can gradually change the expectation to require more out of him. Maybe instead of “buh” you now require him to say “Cook” before giving him the cookie. This process is called “Shaping.”  We are rewarding him for approximations until eventually he is able to say the whole word (or use the icon or sign language).
