Knowing how to stop an autistic child climbing on a window sill is a puzzle facing a number of parents in our position.

In the below article we examine the behaviour and give you some tips to try at home.

Autism and climbing on window sills

Autistic children often experience sensory processing differences that can influence their behaviour.

Climbing on window sills might be a manifestation of their need for sensory input or a way to cope with certain sensations.

For some, the height and texture of the window sill can provide a sensory experience that helps them control their emotions.

The repetitive nature of continuing climbing on the window sill gives them a sense of control in their environment.

Additionally, the outside world visible through the window could be fascinating and captivating, leading them to seek closer interaction with it.

Period of observation

One of the key things you will have to do is really try to understand why your child is sitting on the window sill.

To do this you’ll need to watch them closely.

Do they favour a particular window sill? Is that one different to others?

When does your child engage in the behaviour, is there anything interesting happening at that time outside such as rain?

Is there a particular time of day when they sit on the window sill? Are they stressed, hungry or tired?

Are there birds outside which your child is watching?

These are all possible pieces of the puzzle which will be important to arriving at a solution.

Create a sensory alternative

It is likely that your child is climbing on the window sill to satisfy a sensory desire.

Another possibility may be that they like the cold feeling of the glass or the smooth texture of the sill itself.

It could also be that they just like the feeling of their feet hanging.

Providing alternative sensory experiences can help redirect their attention.

Consider setting up sensory stations with various textures, weights, or materials that can offer the some sensory input.

Communicate by whatever means necessary

Difficulties with communication may be inhibiting your ability to explain to your child why they shouldn’t climb on the window sill.

Autistic children often benefit from visual cues.

Create a visual schedule or cue card that indicates when window sill climbing is not allowed.

This simple method of communication will help your child understand appropriate times and places for this behaviour.

Make physical alterations

Firstly it is important to ensure that windows are secure and childproofed to prevent any accidents.

Another safety measure you could consider is ensuring that the ground below is soft. This could include adding a padded rug or cushions when they are sitting there.

Once you are satisfied that the area is as safe as possible you could then make alterations to try and discourage your child.

These could be as simple as painting the sill or you could get more creative.

You could add appropriate items onto the sill, such as fake plants in robust (plastic) pots.

Your child may move the plants or it may just deter them all together.

You could also rearrange your furniture to make it more difficult for your child to access the window sill.

Another option would be to change the texture of the sill.

Turning it into a feature adding something like a grill or textured wallpaper won’t be to everyone’s taste.

But if you’re looking to stop the climbing at all costs it is an option.

What you are trying to do is break what may well have become an engrained routine.

By altering the environment you may be able to guide your child away from the behaviour.

Provide physical outlets

Providing opportunities for physical activities can help channel sensory needs.

Engaging in activities like jumping on a trampoline, swinging, or climbing at a playground can be beneficial.

It may be that your child is fascinated with the outside, so you could create opportunities for them to explore safely.

Reward good behaviour

If you manage to talk your child down from the window sill or divert them in the first place be sure to reward them with praise.

Positive reinforcement can encourage them to make better choices.

With time they will connect not sitting on the window sill with praise and reward.

Leave them to it

One readily available option is to just let your child carry on with the activity. Autistic children can develop any number of repetitive behaviours.

In the big scheme of things if the window is not high and safety modifications are in place that you are satisfied will protect your child, is it that bad?

This will be a personal decision for you as parents, it could be that you feel the window sitting is inhibiting their development.

But if that isn’t the case and it is a safe thing for them to do, many people in your position would just let them continue.

Summary – How to stop an autistic child climbing on a window sill

Remember, addressing window sill climbing is not about suppressing your child’s unique sensory experiences.

It is more about ensuring their safety and helping them develop appropriate ways to fulfill their sensory needs.

With patience, understanding, and a proactive approach, you can create an environment that supports your child’s needs and keeps them safe.
