I'm old - actually very old. I can remember worries about official involvement in the life of families going way back. And not just me. But we parents already had experience of overbearing and authoritative officialdom from first contact in first pregnancy - we were just to do as we were told and it was up to the experts to make decisions.
Things on the pre-natal front, at least, seem to have changed a great deal since then for most people. But memories don't fade so quickly, and there are bound to be families and communities who still anticipate having very little voice in any communication with officials. For those people, and I'd guess there's a very significant number, it will take a lot of time to gain some trust in doctors/midwives/teachers/social workers.
Some of the initiatives already mentioned here will go a long way to opening up the channels of communication. Certainly there should be emphasis by social workers on the rights of parents to get access to legal representation, and that's a minimum.
Unfortunately, there's no easy way to get across to individuals and communities what social workers can do to make things better for parents and families who are struggling. I've just had a quick browse through my local county council's website and just about the only relevant stuff is explaining the referral systems, and mostly, it seems, reassuring members of the public who made a referral. There appears to be nothing about what support is available to families.
Oh, but there is a link to Surestart centres. Except that most of them been closed down as a cost-cutting exercise.
I think I can have some, if not quite a bit, understanding of all the viewpoints on this thread. I can imagine that: the fear means that barriers automatically go up; just one example of poor behaviour by anyone in "authority" spreads like wildfire; overworked and stressed social workers don't have the time and energy to engage with families in the way they should (and for most them, the way they'd like to).
A long time ago, Spero posted a link to www.familylawweek.co.uk/site.aspx?i=fo6 (which I think has already been posted above). I read judgements there on occasions. I have got the impression that attitudes within the Family Court have changed. Certainly, the mantra these days is that adoption is granted only "when nothing else will do". The judge will have had the opportunity to see and hear the parents in court, and they don't get to be Family Court judges until they have had a lot of years under their belt. They are very used to very stressed and anxious "civilians" finding themselves surrounded by "experts" in a legal setting and, from the judgements I've read, do their best to enable those voices to be heard. They also, when necessary, have criticised professionals for not doing their job properly.
Things were bad in the past. They are now gradually getting better. But it will take a long time for that to filter down enough for vulnerable parents to trust anyone.
[As for the local Surestart that got closed. Well, obviously that wasn't needed in our "white, middle-class, Cathedral" town. Any mum who needs support just needs to get into her car, drive down the motorway, probably with a screaming baby, and find her way through an unfamiliar town, to the nearest available. Any shortfall in the less privileged areas locally thankfully gets taken up by the local churches. Support/prevention/advice is, of course, unquantifiable. But it's what pays dividends.]
