CPS, vaccination, G.K. Chesterton and the institution of the family

Nancy's eldest daughter has posted a comment in the combox below with the latest update.
I'm worried a lot about Neil (the breastfed baby). I have seen pictures that were taken before CPS took him as well as pictures from when they got him back for that short time - with bruises and a black eye.
I really think that part of the dynamics here is a social convention that basically says that having more than 2 or 3 kids is in and of itself child abuse. Most states have laws that regulate foster homes by their physical plant more than any other criterion. For example, you have to have x square feet of bedroom space per child, no more than 2 children per bedroom, a bathroom for every x children etc. Most families with many children would not be able to meet these criteria. I grew up in a large family - as an Air Force brat until I was 14. There were many assignments where our housing was such that we had 3 or 4 kids in a bedroom - and sometimes 2 kids in a bed (at least for short periods).
And then let's talk about vaccinations. If you don't follow the state's guidelines for vaccination, you run the risk of being considered abusive or neglectful. I personally vaccinated my kids, but I know that there are many loving, thoughtful, and caring parents who do not choose to walk in lockstep with the advisory panels. Some are concerned about the fact that many vaccines have ingredients that, however remotely, derive from aborted fetal tissues (mostly collected in the 1960s). Others are concerned about the preservatives used. Still others are really worried about the long term health effects of directly challenging an infants immature immune system with so many different agents in such an unnatural way (through the muscles to the blood stream). They argue that our current epidemic in asthma, allergies, and auto-immune disorders are the long term effect of all these immunizations.
G.K. Chesterton had quite a lot to say about the 'nanny state' second guessing parental concern. You can read much of it in the compilation Brave New Family. Part Six is labeled "The Assassins of the Family". On page 221 of my edition, close to the end of part six, is the following quote:
One by one, the defences of our civilization are being broken down by a concentrated attack on the mind. Rome's barbarians were a menace on her borders; ours are also within the state. (Aug 30, 1930)
He earlier (page 219) had quoted a Church of England clergyman as saying:

If the State assumes the axiom that every child born has a claim upon the State for maintenance, then there must go along with that the claim on the part of the State to say whether a child should be born or not

And on page 266, in a bit about the King's Christmas address (Jan 3, 1935):
We that are Christians believe that the family has a divine sanction. But any reasonable pagan, if he will work it out, will discover that the family existed before the State and has prior rights; that the State exists only as a collection of families, and that its sole function is to safeguard the rights of each and all of them.
Chesterton was in Britain at a time when Nazis were winning hearts and minds on the continent. So he, not unreasonably, was sensitized to the abuses that the State could commit in the name of the greater good. He railed against the Nazi, the Communist, and the Capitalist with equal fervor, for all of them wanted to displace the family. All the -ists and -isms that have become a modern day idolatry are still alive and well and fighting against those who would prefer to defer to the natural law. It is to weep, and wail, and gnash the teeth, and ultimately to pray and to act.
