Child travelling with grand parents -pls advice urgent

[lotstoread]

Hi All

My son is currently in india. He is a british passport holder and will be travelling with my parents to uk. My parents are travelling on family visitor visa.

Do they have to carry any documents as they will be travelling with my son?

I have given them a consent letter (signed by me & my wife) and also copies of our passports. Is that enough? However the copies are not notorised. Is that ok?

Pls reply urgently as they are travelling soon.

Thanks All.
