Best Finish for wooden blocks

I am in the process of making a set of blocks for a toddler out of radiata pine. I want to colour them. I understand that paint/lacquer/polyurethane is not the best solution (toxic to kids chewing on them etc)

I am proposing to stain them with UBEAUT WATER DYE (already have it) and then seal it with shellac.

Would HARD SHELLAC be the best one to use ?

Where can I get UBEAUT Shellac in Melbourne Eastern/Outer Eastern Suburbs? (Nunawading to Lilydale area.... nearby OK too)

Thanks in advance
