Thank you for this post @reginagraced. I hope all parents start to follow this critical advise:

Remember it is your Legal Right to tell a social worker that you need time researching your rights before you can attend to them. More sternly but with a gentle spirit, let them know you can't have anything to do with them without a warrant. Talk less and let them be the one that spill in anger. You do not have any business with them if they have no legal permit to interact with you. Final.. Be a Professional Dad and Mum, you can't afford to be a dummy.
