Child Theme doesn’t see custom blocks

I am developing a Parent block theme for my company and the plan is to utilize child themes for all the sites that will use the parent theme.

The parent theme consists of custom blocks that are being registered by the themes functions.php file. The issue is that when the child theme is active, it does not see the custom blocks that are registered by the parent theme, even though the function that registers those blocks runs properly.

Is there something I need to do from the child theme side to see custom blocks registered by the parent theme? We want to avoid the plugin approach as it doesn’t fit our workflow, and all the research I have done up to this point around custom blocks is all around plugins.

Any help would be greatly appreciated!
