I have first hand insight into this topic. I've posted on MN about it a few times and always feel compelled to comment when I see threads like this.
My first born was removed at birth and adopted. I was 18 with no family support and in a violent relationship with a cruel man who pulled me into a very chaotic lifestyle. I left him but he remained a big problem in my life, I couldn't safeguard myself let alone a baby.
For a long time after my babies adoption I was one of these mums screaming from the rooftops about forced adoption and that social services had done me wrong and not supported me. I stood by that for a long time.
With age came insight and I grew to realise that although they hadn't supported me and weren't particularly holistic in the way they treat me or handled certain aspects of the case, they supported the person who mattered the most, my baby, and ultimately they were right to do what they did.
It was in my babies best interest to be adopted and have permanency early on, as opposed to being shuffled around care homes until I was able to make the changes necessary to care for him. (it took me five years in total to rebuild my life)
It was very easy for me to blame social services and focus on all of the things they said or did wrong, because it was easier to do that than admit the fact I wasn't, in those circumstances, suitable to look after my child. Nobody wants to admit they aren't good enough to be a mum and it's a bitter pill to swallow.
My life is entirely different now. I'm safe and happy and I've gone on to become a mum to a wonderful DS and I'm pregnant again. Social services assessed me and have no concerns, they are no longer involved in my life.
That said, I do believe there is more often than not more to the story than the parents will let on. I've been guilty of minimising in the past, telling people around me how appalling social services were to me and not giving the whole picture. I do suspect that is what that lady is doing, although it is heartbreaking to read her writings and it's clear she adores her little girl.
I've had a look at her Facebook and it seems her daughter was in her care for a period of time after being born, that would suggest social services had concerns with her parenting as opposed to historical mental health, the fact the little girl stayed with her after birth means SS were not hugely concerned about her past MH problems.
Another comment that stood out to me was the one on her justgiving page "I was told not to have children for at least ten years"
Obviously I don't know the story but what I've taken from it was she had a child(ren) who were taken into care, warned not to have another for a substantial period of time, went on to conceive her little girl and was then given a second chance to prove herself, but new concerns were raised about her ability to look after her daughter? Perhaps I'm wrong though?
I do feel for her massively as I know exactly how much it hurts, and I truly hope she finds peace.
Social services can make mistakes as nobody is infallible but in cases like this there is almost always more to the story than the parents are letting on having been there myself can say that with certainty.
