Give permission

[Anna232]

Can I use "permission" without the article in this sentence?

A 3-year-old child should not be given any sweets unless, of course their parents give permission.

It is from an agreement between a parent and a certain kindergarten.

 

[Rover_KE]

Any article would be incorrect, but ‘their’ would be OK, though not compulsory.

 

[teechar]

A 3-year-old child should not be given any sweets unless, of course, their parents give permission.

Note the second comma.
