Well in the time I've been away pretty much all I would have said to reveal the sheer ignorance in that response has been said! Thank you!!!
The only point not mentioned.... I bet you do not know the mother or ever met her as this is not compliant with the adoption process.
I HAVE met the birth mother and she writes to me twice a year and I write to her twice a year. IF YOU KNEW THE FIRST THING ABOUT ADOPTION IN THE UK you would know that in many cases birth parents get the opportunity to meet adoptive parents and in nearly all cases without exception adoptive parents are obliged to have at least annual contact with birth parents regarding the children. Clearly you don't know even the basics.
Thanks for the links, I don't need them mind you. Not because I only know one side of a story, quite the opposite, I've already read them when first put on net because you are wrong that I just accept everything I'm told. I question, I research and I make myself fully informed, I'm a first class honours graduate with post grad qualifications, whose spent time in foster care myself, have friends who've been adopted, have friends who've had SS intervene in their family lives and not lose their children and have worked with vulnerable children.....I'm not a bloody nodding dog!
Also, if you could refrain from using language such as 'doing me a favour'. It's entirely inaccurate, ignorant and offensive both to me and my adopted children. You just implied that these children are being passed around to do people favours?!?!. For gods sake, think before you speak, or perhaps just not speaking about a topic you are clearly not at all informed about if that's possible, that is the only 'favour' I need.
Oh and here's another fact for you...68,840 children were in the care of local authorities on 31st March 2014, that year 5050 children were adopted, so you're looking at 63,790 children who weren't adopted because social workers are working with birth parents to ensure adoption is the last resort.
...Though as you don't seem to read my posts (the mother's day thing?!?) I don't know why I'm bothering. And you said your health visitor  did not seem to listen to my answers until she heard something that could be interpreted as something " alarming" from her point of view....hmmm...pots and kettles.
To all the lovely people to whom I first posted the original question I apologise for my rant.
In a moment there will be some thank yous coming, but first I need a cup of tea
