Would you be comfortable with other family members posting pictures of your baby on Facebook?

I'm more than happy that they take photo with my son. They don't need my permission, in fact I don't see why the need for permission when they are my son's family members and half a parent to my son. I don't want to be a barrier to my son forming an relationship with external family members. With that said, if you know someone have bad intention, then is your duty to protect your son from him/her.
