It depends on how you view the parent/child relationship. In most countries parents have a sort of "ownership" role of their child. A right to raise them in their own way, religion and traditions. It is THEIR child to teach, and raise.
This has become pretty contentious in Norway, and Norway has lost cases child protection cases regarding this in international courts. Our child protection services has taken children from their parents and that has ended up in international courts in some cases. This is due to a difference in opinion in what is acceptable and OK ways to raise a child, and what constitutes the rights of the parents and the rights of the child. In some of these cases Norway have rightfully been convicted. But you won't lose the ability to raise your child in Norway over nothing, as some people will have you believe. The child protective services can't explain why to the public, and the parents can pretend to be innocent.
Personally I believe parents do not own their child. I believe parents are in a privileged position and lucky to be allowed to raise a human (yes, also biological), and that the privilege should be revoked if the parents are not sufficiently fit to raise the child.
The perspective of ownership is harmful in my opinion and does often conflict with the interests of the child in my opinion.
Should the child get vaccinated? Yes, exceptions are only allergies.
Should the child be home schooled? No.
Should the child interact with peers at the kindergarten and school and get the social skills they need? Yes
What sorts of punishments are acceptable?
Should the child be heavily involved in religion? No, but should learn about it, and can in a limited degree practice it. But no religious schools, or religious camps. Genital mutilation should not be allowed for boys either. If they want to, they can do it as adults. Doing unnecessary surgery on a defenseless child due to religion is in no way acceptable.
If the parents are neglecting their child, how much neglect is okay before the right/privilege is revoked?
If the parents are addicts, what then?
Etc.
