Whose children are they anyway

This rather worries me, when filling in the form to remove themselves from the NHS Spine database somebody wondered about doing the same for their children,

I was confused about whether I could fill this in for my daughter. So, I rang the NHS Care Records Service Information Line on 0845 603 8510 and enquired as to how I should proceed. The gentleman on the other end told me that I could complete the form for my daughter but my GP had the right to ignore my request if he or she thought it in the best interests of the child

.
As they say,

So who is responsible for my daughter?
