"To the best of one's ability" - Synonym?

I'm trying to rephrase

We help children move and play to the best of their ability.

It's about children with movement concerns, so this seems semantically correct to me.

I just need a different phrase.

Can you suggest anything other than "as well as they can"?

I've reviewed the suggested duplicate, but it doesn't answer my question.

Solution 1:

How about as freely as possible?

"We help children move and play as freely as possible".

Collins:

freely
4. adverb [ADVERB after verb]
If something or someone moves freely, they move easily and smoothly, without any obstacles or resistance.
The clay court was slippery and he was unable to move freely.

Solution 2:

You could consider utmost either as a noun or as an adjective.

As a noun:
"We help children move and play to their utmost."

As an adjective:
"We help children move and play to their utmost ability."

Merriam-Webster:

utmost adjective
ut·​most | \ˈət-ˌmōst, especially Southern -məst\
Definition of utmost (Entry 1 of 2)
2 : of the greatest or highest degree, quantity, number, or amount

utmost noun
Definition of utmost (Entry 2 of 2)
2 : the highest, greatest, or best of one's abilities, powers, and resources

Solution 3:

If you want to use a phrase that means the same thing and also doesn't imply somebody's disability, you could say:

We help children maximize their potential.

This can apply not only to movement but to anything else they do. If you want to mention play or movement specifically, you can qualify it by prefacing it with something like when it comes to recreation.

Using it in the context of children with disabilities is fine, but it can be equally used for anyone, so it doesn't have any kind of unstated assumptions behind it.
