You are innocent. You have nothing to hide. So you cooperate. You let them in your house without a Search Warrant.
"The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
You have no clue how evil and insane they are, so you TALK with them, answer their questions, try to explain why they are wrong. Because you know nothing about your Fifth Amendment Rights-
"No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation."
Which 5th Amendment Right was the basis of Miranda Rights.
Put simply- If you pour your heart out to a CPS worker, you bet she is taking notes. Everything you blab to her is going to come back at you all twisted up in her PETITION to the COURT.
The term "You can't un-ring the bell" applies here.
If you do what 999 out of a 1000 people do, you are IN THE SYSTEM.
It's not magic. It's WHAT PEOPLE DO. Like Lemmings. Or Sheeple jumping off a cliff.
