Patience and a long view. Computational understanding only has much value for your child at multiples >= 3x of their current age. Right now, the primary value will be spending time with you and you sharing your interests with them. Good luck.
That is the true value to your child - to give them an entire new perspective on problem solving, that help them to realize their own performance is not a thing to be judged, but a result to be improved.
I'm NOT a math genius (or any kind of genius), but it went from being unapproachable to being totally learnable.
