Apple Watch for child

[Miso]

Is it possible to add an Apple Watch for my child on O2? I am with o2 and have an iPhone of my own and my own Apple Watch is linked to that. I am trying to work out if I can get a cellular watch with o2 with its own number for my daughter to use without a phone of her own. There is a lot of contradictory information on this topic.

As I understand, yes you can. 
It would need to be linked to your child’s number, which if on your account is possible but best done in store. 
Take photo ID with you as may be needed.

Thank you, that’s helpful. I will go to a store to set up
